Meaning of the longest word in english

From Wikipedia, the free encyclopedia

The identity of the longest word in English depends on the definition of a word and of length.

Words may be derived naturally from the language’s roots or formed by coinage and construction. Additionally, comparisons are complicated because place names may be considered words, technical terms may be arbitrarily long, and the addition of suffixes and prefixes may extend the length of words to create grammatically correct but unused or novel words.

The length of a word may also be understood in multiple ways. Most commonly, length is based on orthography (conventional spelling rules) and counting the number of written letters. Alternate, but less common, approaches include phonology (the spoken language) and the number of phonemes (sounds).

Major dictionaries

The longest word in any of the major English language dictionaries is pneumonoultramicroscopicsilicovolcanoconiosis (45 letters), a word that refers to a lung disease contracted from the inhalation of very fine silica particles,^[12] specifically from a volcano; medically, it is the same as silicosis. The word was deliberately coined to be the longest word in English, and has since been used^{[citation needed]} in a close approximation of its originally intended meaning, lending at least some degree of validity to its claim.^[6]

The Oxford English Dictionary contains pseudopseudohypoparathyroidism (30 letters).

Merriam-Webster’s Collegiate Dictionary does not contain antidisestablishmentarianism (28 letters), as the editors found no widespread, sustained usage of the word in its original meaning. The longest word in that dictionary is electroencephalographically (27 letters).^[13]

The longest non-technical word in major dictionaries is flocci­nauci­nihili­pili­fication at 29 letters. Consisting of a series of Latin words meaning «nothing» and defined as «the act of estimating something as worthless»; its usage has been recorded as far back as 1741.^[14][15][16]

Ross Eckler has noted that most of the longest English words are not likely to occur in general text, meaning non-technical present-day text seen by casual readers, in which the author did not specifically intend to use an unusually long word. According to Eckler, the longest words likely to be encountered in general text are deinstitutionalization and counterrevolutionaries, with 22 letters each.^[17]

A computer study of over a million samples of normal English prose found that the longest word one is likely to encounter on an everyday basis is uncharacteristically, at 20 letters.^[18]

The word internationalization is abbreviated «i18n», the embedded number representing the number of letters between the first and the last.^[19][20][21]

Creations of long words

Coinages

In his play Assemblywomen (Ecclesiazousae), the ancient Greek comedic playwright Aristophanes created a word of 171 letters (183 in the transliteration below), which describes a dish by stringing together its ingredients:

Henry Carey’s farce Chrononhotonthologos (1743) holds the opening line: «Aldiborontiphoscophornio! Where left you Chrononhotonthologos?»

Thomas Love Peacock put these creations into the mouth of the phrenologist Mr. Cranium in his 1816 book Headlong Hall: osteosarchaematosplanchnochondroneuromuelous (44 characters) and osseocarnisanguineoviscericartilaginonervomedullary (51 characters).

James Joyce made up nine 100-letter words plus one 101-letter word in his novel Finnegans Wake, the most famous of which is Bababadalgharaghtakamminarronnkonnbronntonnerronntuonnthunntrovarrhounawnskawntoohoohoordenenthurnuk. Appearing on the first page, it allegedly represents the symbolic thunderclap associated with the fall of Adam and Eve. As it appears nowhere else except in reference to this passage, it is generally not accepted as a real word. Sylvia Plath made mention of it in her semi-autobiographical novel The Bell Jar, when the protagonist was reading Finnegans Wake.

«Supercalifragilisticexpialidocious», the 34-letter title of a song from the movie Mary Poppins, does appear in several dictionaries, but only as a proper noun defined in reference to the song title. The attributed meaning is «a word that you say when you don’t know what to say.» The idea and invention of the word is credited to songwriters Robert and Richard Sherman.

Agglutinative constructions

The English language permits the legitimate extension of existing words to serve new purposes by the addition of prefixes and suffixes. This is sometimes referred to as agglutinative construction. This process can create arbitrarily long words: for example, the prefixes pseudo (false, spurious) and anti (against, opposed to) can be added as many times as desired. More familiarly, the addition of numerous «great»s to a relative, such as «great-great-great-great-grandparent», can produce words of arbitrary length. In musical notation, an 8192nd note may be called a semihemidemisemihemidemisemihemidemisemiquaver.

Antidisestablishmentarianism is the longest common example of a word formed by agglutinative construction.

Technical terms

A number of scientific naming schemes can be used to generate arbitrarily long words.

The IUPAC nomenclature for organic chemical compounds is open-ended, giving rise to the 189,819-letter chemical name Methionylthreonylthreonyl…isoleucine for the protein also known as titin, which is involved in striated muscle formation. In nature, DNA molecules can be much bigger than protein molecules and therefore potentially be referred to with much longer chemical names. For example, the wheat chromosome 3B contains almost 1 billion base pairs,^[22] so the sequence of one of its strands, if written out in full like Adenilyladenilylguanilylcystidylthymidyl…, would be about 8 billion letters long. The longest published word, Acetylseryltyrosylseryliso…serine, referring to the coat protein of a certain strain of tobacco mosaic virus (P03575), is 1,185 letters long, and appeared in the American Chemical Society’s Chemical Abstracts Service in 1964 and 1966.^[23] In 1965, the Chemical Abstracts Service overhauled its naming system and started discouraging excessively long names. In 2011, a dictionary broke this record with a 1909-letter word describing the trpA protein (P0A877).^[3]

John Horton Conway and Landon Curt Noll developed an open-ended system for naming powers of 10, in which one sexmilliaquingentsexagintillion, coming from the Latin name for 6560, is the name for 10^3(6560+1) = 10¹⁹⁶⁸³. Under the long number scale, it would be 10^6(6560) = 10³⁹³⁶⁰.

Gammaracanthuskytodermogammarus loricatobaicalensis is sometimes cited as the longest binomial name—it is a kind of amphipod. However, this name, proposed by B. Dybowski, was invalidated by the International Code of Zoological Nomenclature in 1929 after being petitioned by Mary J. Rathbun to take up the case.^[24]

Myxococcus llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogochensis is the longest accepted binomial name for an organism. It is a bacterium found in soil collected at Llan­fair­pwll­gwyn­gyll­ (discussed below). Parastratiosphecomyia stratiosphecomyioides is the longest accepted binomial name for any animal, or any organism visible with the naked eye. It is a species of soldier fly.^[25] The genus name Parapropalaehoplophorus (a fossil glyptodont, an extinct family of mammals related to armadillos) is two letters longer, but does not contain a similarly long species name.

Aequeosalinocalcalinoceraceoaluminosocupreovitriolic, at 52 letters, describing the spa waters at Bath, England, is attributed to Dr. Edward Strother (1675–1737).^[26] The word is composed of the following elements:

• Aequeo: equal (Latin, aequo^[27])
• Salino: containing salt (Latin, salinus)
• Calcalino: calcium (Latin, calx)
• Ceraceo: waxy (Latin, cera)
• Aluminoso: alumina (Latin)
• Cupreo: from «copper»
• Vitriolic: resembling vitriol

Notable long words

Place names

The longest officially recognized place name in an English-speaking country is Taumata­whakatangihanga­koauau­o­tamatea­turi­pukaka­piki­maunga­horo­nuku­pokai­whenua­ki­tana­tahu (85 letters), which is a hill in New Zealand. The name is in the Māori language. A widely recognized version of the name is Taumatawhakatangihangakoauauotamateaturipukakapikimaungahoronukupokaiwhenuakitanatahu (85 letters), which appears on the signpost at the location (see the photo on this page). In Māori, the digraphs ng and wh are each treated as single letters.

In Canada, the longest place name is Dysart, Dudley, Harcourt, Guilford, Harburn, Bruton, Havelock, Eyre and Clyde, a township in Ontario, at 61 letters or 68 non-space characters.^[28]

The 58-letter name Llan­fair­pwll­gwyn­gyll­gogery­chwyrn­drob­wlll­lanty­silio­gogo­goch is the name of a town on Anglesey, an island of Wales. In terms of the traditional Welsh alphabet, the name is only 51 letters long, as certain digraphs in Welsh are considered as single letters, for instance ll, ng and ch. It is generally agreed, however, that this invented name, adopted in the mid-19th century, was contrived solely to be the longest name of any town in Britain. The official name of the place is Llanfairpwllgwyngyll, commonly abbreviated to Llanfairpwll or Llanfair PG.

The longest non-contrived place name in the United Kingdom which is a single non-hyphenated word is Cottonshopeburnfoot (19 letters) and the longest which is hyphenated is Sutton-under-Whitestonecliffe (29 characters).

The longest place name in the United States (45 letters) is Char­gogga­gogg­man­chau­ggagogg­chau­buna­gunga­maugg, a lake in Webster, Massachusetts. It means «Fishing Place at the Boundaries – Neutral Meeting Grounds» and is sometimes facetiously translated as «you fish your side of the water, I fish my side of the water, nobody fishes the middle». The lake is also known as Webster Lake.^[29] The longest hyphenated names in the U.S. are Winchester-on-the-Severn, a town in Maryland, and Washington-on-the-Brazos, a notable place in Texas history. The longest single-word town names in the U.S. are Kleinfeltersville, Pennsylvania and Mooselookmeguntic, Maine.

The longest official geographical name in Australia is Ma­mungku­kumpu­rang­kunt­junya.^[30] It has 26 letters and is a Pitjantjatjara word meaning «where the Devil urinates».^[31]

Liechtenstein is the longest country name with single name in English. The second longest country name with single name in English is Turkmenistan. There are longer country names if one includes ones with spaces.

Personal names

Guinness World Records formerly contained a category for longest personal name used.

• From about 1975 to 1985, the recordholder was Adolph Blaine Charles David Earl Frederick Gerald Hubert Irvin John Kenneth Lloyd Martin Nero Oliver Paul Quincy Randolph Sherman Thomas Uncas Victor William Xerxes Yancy Zeus Wolfe­schlegelstein­hausenberger­dorffvoraltern­waren­gewissenhaft­schaferswessen­schafewaren­wohlgepflege­und­sorgfaltigkeit­beschutzen­von­angreifen­durch­ihrraubgierigfeinde­welche­voraltern­zwolftausend­jahres­vorandieerscheinen­wander­ersteer­dem­enschderraumschiff­gebrauchlicht­als­sein­ursprung­von­kraftgestart­sein­lange­fahrt­hinzwischen­sternartigraum­auf­der­suchenach­diestern­welche­gehabt­bewohnbar­planeten­kreise­drehen­sich­und­wohin­der­neurasse­von­verstandigmen­schlichkeit­konnte­fortplanzen­und­sicher­freuen­anlebens­langlich­freude­und­ruhe­mit­nicht­ein­furcht­vor­angreifen­von­anderer­intelligent­geschopfs­von­hinzwischen­sternartigraum, Senior (746 letters), also known as Wolfe+585, Senior.
• After 1985 Guinness briefly awarded the record to a newborn girl with a longer name. The category was removed shortly afterward.

Long birth names are often coined in protest of naming laws or for other personal reasons.

• The naming law in Sweden was challenged by parents Lasse Diding and Elisabeth Hallin, who proposed the given name «Brfxxccxxmnpcccclllmmnprxvclmnckssqlbb11116» for their child (pronounced [ˈǎlːbɪn], 43 characters), which was rejected by a district court in Halmstad, southern Sweden.

Words with certain characteristics of notable length

• Schmaltzed and strengthed (10 letters) appear to be the longest monosyllabic words recorded in The Oxford English Dictionary, while scraunched and scroonched appear to be the longest monosyllabic words recorded in Webster’s Third New International Dictionary; but squirrelled (11 letters) is the longest if pronounced as one syllable only (as permitted in The Shorter Oxford English Dictionary and Merriam-Webster Online Dictionary at squirrel, and in Longman Pronunciation Dictionary). Schtroumpfed (12 letters) was coined by Umberto Eco, while broughammed (11 letters) was coined by William Harmon after broughamed (10 letters) was coined by George Bernard Shaw.
• Strengths is the longest word in the English language containing only one vowel letter.^[32]
• Euouae, a medieval musical term, is the longest English word consisting only of vowels, and the word with the most consecutive vowels. However, the «word» itself is simply a mnemonic consisting of the vowels to be sung in the phrase «seculorum Amen» at the end of the lesser doxology. (Although u was often used interchangeably with v, and the variant «Evovae» is occasionally used, the v in these cases would still be a vowel.)
• The longest words with no repeated letters are dermatoglyphics and uncopyrightable.^[33]
• The longest word whose letters are in alphabetical order is the eight-letter Aegilops, a grass genus. However, this is arguably a proper noun. There are several six-letter English words with their letters in alphabetical order, including abhors, almost, begins, biopsy, chimps and chintz.^[34] There are few 7-letter words, such as «billowy» and «beefily». The longest words whose letters are in reverse alphabetical order are sponged, wronged and trollied.
• The longest words recorded in OED with each vowel only once, and in order, are abstemiously, affectiously, and tragediously (OED). Fracedinously and gravedinously (constructed from adjectives in OED) have thirteen letters; Gadspreciously, constructed from Gadsprecious (in OED), has fourteen letters. Facetiously is among the few other words directly attested in OED with single occurrences of all six vowels (counting y as a vowel).
• The longest single palindromic word in English is rotavator, another name for a rotary tiller for breaking and aerating soil.

Typed words

• The longest words typable with only the left hand using conventional hand placement on a QWERTY keyboard are tesseradecades, aftercataracts, dereverberated, dereverberates^[35] and the more common but sometimes hyphenated sweaterdresses.^[34] Using the right hand alone, the longest word that can be typed is johnny-jump-up, or, excluding hyphens, monimolimnion^[36] and phyllophyllin.
• The longest English word typable using only the top row of letters has 11 letters: rupturewort. The word teetertotter (used in North American English) is longer at 12 letters, although it is usually spelled with a hyphen.
• The longest using only the middle row is shakalshas (10 letters). Nine-letter words include flagfalls; eight-letter words include galahads and alfalfas.
• Since the bottom row contains no vowels, no standard words can be formed. ^[37]
• The longest words typable by alternating left and right hands are antiskepticism and leucocytozoans respectively.^[34]
• On a Dvorak keyboard, the longest «left-handed» words are epopoeia, jipijapa, peekapoo, and quiaquia.^[38] Other such long words are papaya, Kikuyu, opaque, and upkeep.^[39] Kikuyu is typed entirely with the index finger, and so the longest one-fingered word on the Dvorak keyboard. There are no vowels on the right-hand side, and so the longest «right-handed» word is crwths.

Would you believe that there are 21 of the longest words in English language that have more than 20 letters? As it turns out, these long words can be quite useful for showing off your vocabulary skills. But what do they mean? In this blog post, we’ll take a closer look at 21 of the longest words in English and what they mean. So whether you’re looking to impress your friends or just learn something new, keep reading!

Here are the 21 of the Longest Words in English:

1. Pneumonoultramicroscopicsilicovolcanoconiosis

Pneumonoultramicroscopicsilicovolcanoconiosis is one of the longest words in English, and it’s also one of the most difficult to pronounce. But what does it actually mean? The word was first used in 1935 by a doctor named E.M. Hoda, who defined it as “a chronic lung disease caused by the inhalation of very fine silica dust.” However, the word is now considered to be obsolete, and it’s rarely used in medical contexts.

Nevertheless, it remains a fascinating example of the flexibility of language. With a little creativity, it’s possible to create words that are both long and meaningful. And in an era of text messaging and Twitter, brevity is often overrated. So the next time you need to express a complex idea, don’t be afraid to reach for the dictionary. With a little effort, you might just find the perfect word.

2. Hippopotomonstrosesquippedaliophobia

Hippopotomonstrosesquippedaliophobia is one of the longest words in English. But it’s not just the length that makes it impressive, it’s also the meaning. The word describes a fear of long words, which might seem like a silly thing to be afraid of. But for those who suffer from hippopotomonstrosesquippedaliophobia, the fear is very real.

The word itself is derived from the Greek ‘hippopotamos’, meaning ‘river horse’, and ‘monstrōsēs’, meaning ‘monstrous’. The ‘equippedalis’ part comes from the Latin ‘equus’, meaning ‘horse’, and ‘pedalis’, meaning ‘foot’. So the word literally means ‘fear of long words that are like monsters with horse feet’.

It’s not known exactly how many people suffer from hippopotomonstrosesquippedaliophobia, but it is thought to be relatively rare. For those who do have the condition, it can be extremely debilitating. Just hearing a long word can trigger anxiety and panic, and in severe cases, even lead to avoidance behavior. If you know someone who has hippopotomonstrosesquippedaliophobia, it’s important to be understanding and patient. With treatment and support, they can overcome their fear and live a normal life.

3. Pseudopseudohypoparathyroidism

If you’re looking for a challenge, try pronouncing pseudopseudohypoparathyroidism. At 30 letters, it’s one of the longest words in the English language. And it’s not just a jumble of random syllables – it actually has a meaning.

Pseudopseudohypoparathyroidism is a condition that causes people to have the symptoms of hypoparathyroidism, even though their parathyroid glands are functioning normally. So what’s the pseudo all about? It comes from the Greek word for false, because the symptoms are false alarms.

Despite its length, pseudopseudohypoparathyroidism is a relatively rare condition – but that doesn’t make it any less confusing for those who have it.

4.Supercalifragilisticexpialidocious

Supercalifragilisticexpialidocious is one of the longest words in English, and it’s a perfect example of why length isn’t everything when it comes to words. The word was coined by Mary Poppins author P.L. Travers and first appeared in the 1964 Disney film adaptation of her book.

It’s a made-up word intended to convey the idea of something “extraordinary and wonderful,” and it succeeds admirably on both counts. The word is so playful and fun to say that it immediately puts a smile on your face, which is more than can be said for a lot of longer words.

In addition, its length makes it perfect for use in all sorts of creative endeavors, from children’s songs to crossword puzzles. So even though it may not be the most useful word in the English language, there’s no denying that supercalifragilisticexpialidocious is one of the most memorable.

5.Hepaticocholangiogastrostomy

Hepaticocholangiogastrostomy is one of the longest words in the English language, clocking in at 28 letters. That’s quite a mouthful! And it’s not even the longest word in medical terminology – that honor goes to pneumonoultramicroscopicsilicovolcanoconiosis, at 45 letters. So what does hepaticocholangiogastrostomy mean?

It’s a surgical procedure that involves connecting the hepatic duct (the main bile duct) to the stomach. The procedure is typically performed when there is a blockage in the bile duct that prevents bile from flowing into the intestine. By connecting the hepatic duct directly to the stomach, bypasses the blockage and allows bile to flow into the intestine as normal.

Hepaticocholangiogastrostomy is just one example of the many long words that can be found in medical dictionaries. So next time you’re feeling stuck for something to say, why not impress your friends with your knowledge of this very long word!

6. Radioimmunoelectrophoresis

As one of the longest words in English, “radioimmunoelectrophoresis” is certainly an impressive-sounding piece of vocabulary. But what does it actually mean? Radioimmunoelectrophoresis is a technique used to separate charged particles according to their size and charge. It relies on the fact that charged particles will be deflected when placed in an electric field.

By varying the strength of the electric field, radioimmunoelectrophoresis can be used to separates a wide range of particles, from small ions to large proteins. This makes it a valuable tool for research in many different fields, ranging from biology to geology.

So next time you see the word “radioimmunoelectrophoresis,” don’t be intimidated – just think of it as a long way of saying “electric field separation.

7. Antidisestablishmentarianism

Antidisestablishmentarianism is one of the longest words in English, and it’s also one of the most interesting. The word is made up of three parts: “anti-,” “disestablishment,” and “-arianism.” The “anti-” part is fairly self-explanatory; it means against or opposed to. “Disestablishment” is a bit more complicated. In this context, it means the act of ending state support for a particular church or religion. “-arianism” is a suffix that refers to a belief or doctrine.

So, put all together, antidisestablishmentarianism is the belief that the state should not support any particular church or religion.

Interestingly, the word was actually coined in the 19th century in opposition to the Disestablishment Act of 1833, which ended state support for the Church of England.

So, in a way, the word itself is a testament to the power of established institutions. After all, if the people who opposed the Disestablishment Act hadn’t come up with such a long and memorable word, it’s unlikely that the act would have been overturned.

In any case, antidisestablishmentarianism is a fascinating example of how a single word can encapsulate a complex political belief.

8. Spectrophotofluorometrically

English is a weird language. It’s full of words that are hard to pronounce, and it often doesn’t follow any logical rules. One of the longest words in English is “spectrophotofluorometrically.” It’s made up of four parts: “spectro,” meaning “light”; “photo,” meaning “light”; “fluoro,” meaning “fluorescence”; and “metrical,” meaning “measurement.”

The word is used to describe a process of measuring the amount of light that is absorbed by a material when it is exposed to light. While the word may be difficult to say, it’s actually quite simple conceptually. So next time you’re feeling challenged by a long word, just remember that it might not be as complicated as it seems.

9.Floccinaucinihilipilification

Floccinaucinihilipilification is one of the longest words in the English language, and it’s also one of the most fun to say. The word comes from the Latin root words “floccus,” “naucum,” “nihilum,” and “pilus,” which all have to do with wool or hair. “Floccus” means “woolen tuft;” “naucum” means “nape of the neck;” “nihilum” means “nothing;” and “pilus” means “hair.”

Put them all together, and you get a word that means “the estimation of something as worthless.” In other words, it’s the act of regarding something as unimportant or not worth considering.

The word first appeared in print in 1741, in a work called A Classical Dictionary of the Vulgar Tongue by Francis Grose.

Since then, it has been used sparingly but has popped up from time to time in works by some fairly famous authors. In 1826, Edward Gibbon used it in The Decline and Fall of the Roman Empire: “…the decline of Rome was hastened by savage infants who, born in slavery, could not be impressed by the floccinaucinihilipilification of liberty.”

10.Psychoneuroendocrinological

The word psychoneuroendocrinological is one of the longest words in the English language, and it’s also one of the most interesting. It’s a combination of three different words: psycho, which refers to the mind; neuro, which refers to the nervous system; and endocrine, which refers to the glands that produce hormones.

Together, these three word parts form a word that refers to the study of how the mind, nervous system, and hormones interact.

Psychoneuroendocrinology is a relatively new field of study, and it’s still uncovering a lot of fascinating information about how our minds and bodies work together. For example, recent research has shown that stress can cause physical changes in our bodies, including changes in hormone levels.

This research is helping us to understand how stress affects our health and well-being, and it’s also providing insight into how we can better manage stress. As we continue to learn more about psychoneuroendocrinology, we’re sure to uncover even more fascinating information about the mind-body connection.

11. Incomprehensibilities

Incomprehensibilities. There’s a word for you. It’s one of the longest words in English, and it pretty much sums up the last year for me. I’ve been working on a project that, frankly, has been incomprehensible at times. The goal has been to come up with a way to help people who feel stuck in their lives to find a new way forward.

And, while I’m not done yet, I’m starting to see results. Incomprehensibilities, though? That’s still the word that comes to mind when I think about the challenges I’ve faced along the way. But, hey, if you’re going to take on a big challenge, you might as

12. Immunoelectrophoretically

If you’re looking for a challenge, try saying “immunoelectrophoretically” five times fast. This tongue-twister of a word is one of the longest in the English language, clocking in at 25 letters. Though it may be a mouthful, immunoelectrophoresis is a relatively simple concept.

It’s a type of electrophoresis, which is a technique used to separate molecules based on their electric charge. In this case, the molecules being separated are antibodies, which are proteins produced by the immune system in response to foreign substances.

Immunoelectrophoresis is used to diagnose autoimmune disorders and other conditions in which the body produces abnormal amounts of antibodies. So next time you’re feeling ambitious, give this word a shot – but be prepared for a bit of a workout for your jaw muscles.

13. Uncopyrightable

As a marketer, I’m always looking for words that are both attention-grabbing and accurate. So when I came across the word “uncopyrightable,” I knew I had found a winner.

This word, which is featured in the Merriam-Webster dictionary, describes something that can’t be copyrighted. And while that might not seem all that useful at first glance, it actually has a lot of implications for marketers.

For one thing, it means that you can use this word in your marketing without having to worry about violating someone’s copyright. That’s because there’s no such thing as a copyright on this word. It’s in the public domain, which means anyone can use it however they want.

But beyond that, the word “uncopyrightable” also has a strong message attached to it. When you use this word, you’re effectively saying that your product or service is so unique and valuable that it can’t be copied. That’s a powerful statement to make, and it’s one that is sure to grab people’s attention.

So if you’re looking for a way to stand out from the competition, consider using the word “uncopyrightable” in your marketing. It’s a great way to get people’s attention and make a strong statement about your business at the same time.

14. Uncharacteristically

Uncharacteristically is one of the longest words in English. It’s often used to describe someone who’s not acting like themselves. For example, if you normally see your friend at the gym every day, but today they’re uncharacteristically skipping their workout, that means something’s up.

Maybe they’re sick, or maybe something else is going on. Either way, it’s not usual for them. Another example might be if someone is uncharacteristically late to a meeting. That might mean they had a hard time getting there, or it could be a sign that they don’t really care about the meeting.

Whatever the case may be, uncharacteristically is a great word to describe when someone isn’t acting like their normal selves.

15. Psycholinguistics

Psycholinguistics is the study of how we produce and understand language. It’s a fascinating field that looks at everything from the way infants learn to speak to the way adults use language in everyday life. Psycholinguists also investigate the role of language in thought and cognition, and the relationship between language and culture.

And because language is such a central part of our lives, psycholinguistics has implications for many different disciplines, from psychology and neuroscience to anthropology and sociology. So whether you’re interested in how we acquire language or how we use it, psycholinguistics is a field that definitely merits further exploration.

16. Pneumoencephalographically

Pneumoencephalographically is one of the longest words in English, but what does it actually mean? This medical term refers to an imaging technique that is used to study the brain. It involves injecting air into the space between the brain and the skull.

This procedure creates a clear image of the brain, which can be used to diagnostic problems or track the progression of diseases. While pneumoencephalography is no longer used as often as it once was, it remains an important tool in the diagnosis of neurological disorders.

17. Psychophysicotherapeutics

25 letters long, “psychophysicotherapeutics” is one of the longest words in the English language. And it’s not just a made-up word for Scrabble players; it’s a real, albeit rare, term. So what does it mean? “Psychophysicotherapeutics” is actually two words smashed together: “psychophysical,” meaning relating to or involving both the mental and physical aspects of someone or something, and “therapeutics,” meaning the treatment of disease.

Put them together and you have a word that refers to the treatment of mental and physical diseases. Interestingly, “psychophysicotherapeutics” isn’t just long; it’s also one of the most precise words in the English language. There’s no wasted verbiage here; every letter serves a purpose. So next time you’re looking for a term that perfectly describes the treatment of both mind and body, reach for “psychophysicotherapeutics.”

18. Thyroparathyroidectomized

At 25 letters long, “thyroparathyroidectomized” is one of the longest words in the English language. But what does it mean? “Thyroparathyroidectomized” is a medical term that refers to the removal of the thyroid gland and the parathyroid glands. This surgery is typically performed to treat hyperparathyroidism, a condition in which the parathyroid glands secrete too much hormone.

The surgery is also sometimes used to treat thyroid cancer. While “thyroparathyroidectomized” may be a mouthful, it’s a good reminder that the English language is always evolving. As our understanding of the human body grows, so too do our medical terms. So next time you come across a long word like “thyroparathyroidectomized,” don’t be discouraged. Just think of it as another example of the English language at its best.

19.Otorhinolaryngological

At 23 letters long, “otorhinolaryngological” is one of the longest words in the English language. It’s a mouthful to say, and it’s also a mouthful to define: the word refers to the study of the ear, nose, and throat. This branch of medicine is important for diagnosing and treating conditions that affect these parts of the body, including hearing loss, allergies, and sinus infections. While “otorhinolaryngological” may be a difficult word to pronounce, it’s an important one to know. After all, it’s responsible for keeping our sense of hearing, smell, and taste sharp.

20. Dermatoglyphics

Dermatoglyphics is one of the longest words in English, and it refers to the study of fingerprints. The word itself is derived from two Greek words: derma, meaning “skin,” and glyph, meaning “carving.” The study of fingerprints has a long history, dating back to ancient times.

In China, for example, fingerprint patterns were used for identification purposes as early as the ninth century. Today, dermatoglyphics is still used for a variety of purposes, including law enforcement and forensic science. In addition, the study of fingerprints can also provide insights into individual personality traits and health conditions.

So next time you come across this long word, remember that it’s not just pronounced “der-muh-tuh-GLIF-iks.” It also has a fascinating history and a range of practical applications.

21. Bronchopneumonitis

Bronchopneumonitis is one of the longest words in English, clocking in at 21 letters. But it’s more than just a mouthful-it’s also a serious lung condition that can be caused by airborne viruses or bacteria. In Bronchopneumonitis, the bronchi (the large airways leading to the lungs) become inflamed and fill with fluid.

This can lead to difficulty breathing, coughing, and chest pain. In severe cases, Bronchopneumonitis can be life-threatening. While there is no cure for Bronchopneumonitis, early diagnosis and treatment is essential for preventing serious complications. So if you start feeling short of breath, don’t hesitate to see your doctor-you might just save your life.

Conclusion

As you can see, there are a lot of long words in the English language that have interesting uses. While some of them are so long that they are rarely used, they can still have a significant impact when they are. If you ever need to use one of these words, make sure you use it properly and don’t overuse it. Otherwise, you may risk sounding like you’re trying too hard or using big words for no reason.

FAQs

What are the longest words in English?

The longest word in English is “antidisestablishmentarianism,” which is made up of 28 letters. Other long words include: “floccinaucinihilipilification” (29 letters), “pneumonoultramicroscopicsilicovolcanoconiosis” (45 letters), and “supercalifragilisticexpialidocious” (34 letters).

What do these long words mean?

Antidisestablishmentarianism means opposition to the disestablishment of the Church of England. Floccinaucinihilipilification means the act or instance of estimating as worthless. Pneumonoultramicroscopicsilicovolcanoconiosis is a lung disease caused by breathing in very fine particles of silicon dioxide. Supercalifragilisticexpialidocious means extremely wonderful.

Why are there so many long words in English?

There are a few reasons. First, English has a lot of loanwords from other languages. These foreign words often retain their original spelling, even if that means they’re longer than their English equivalents. Second, English speakers love to coin new words by combining existing ones. This can create very long words, like “antidisestablishmentarianism.” Finally, some long words are just the result of regular old word formation processes. For example, the word “pneumonoultramicroscopicsilicovolcanoconiosis” is made up of various smaller words meaning “lung,” “ultra-microscopic,” and “volcano.” When these words are put together, they create a new word that’s much longer than any of its parts.

What are some other long words in English?

Here are a few more long words: “honorificabilitudinitatibus” (27 letters), “pseudopseudohypoparathyroidism” (30 letters), “thyroparathyroidectomized” (25 letters), and “antidiarrheal” (12 letters).

It should come as no surprise that we are word lovers. In fact, we are big word lovers in that we love really big words. To express our love, we looked around for some of the biggest, most ludicrously long words in the English language. In addition to pure length, we also tried to find: 

• the longest word without vowels
• the longest one-syllable word
• and other uniquely long words.

Figuring out which word is the longest of them all isn’t as simple as just counting letters, though. Should you count scientific words? Should obscure, rarely used words be included, or should we give the honor to a word people actually use? In the interest of fairness, our list includes scientific words, obscure words, and all of the absurdly long words stuck in between.  

methionylthreonylthreonylglutaminylarginyl… 

At over 180,000 letters long, the chemical name of the protein titin is often said to technically be the longest English word. If spoken out loud, this word takes over three hours to say! Its absurd length is due to the fact that proteins get their scientific names by combining the names of all of their joined amino acids together, and titin has quite a lot of them. For obvious reasons, titin’s official name has never actually appeared in a dictionary or scientific text. Because it is a scientific term, many would disqualify the Big M from actually taking the crown as English’s longest word. 

pneumonoultramicroscopicsilicovolcanoconiosis

Pneumonoultramicroscopicsilicovolcanoconiosis, coming in at 45 letters long, is typically the biggest word you will find that actually appears in an English dictionary. According to many sources, it was coined around 1935 by Everett Smith, who at the time was the president of the National Puzzlers’ League. The word, which was basically engineered for its length, refers to a lung disease caused by inhaling silica dust. 

sesquipedalianism

Let’s look at a word related to the business of “longest words.” Sesquipedalianism is the tendency to use long words. Do you have sesquipedalian tendencies? (We do.)

The word is traced to the ancient Roman poet Horace, who in a treatise on the art of poetry wrote that in certain circumstances, poets must avoid sesquipedalia verba, a Latin phrase meaning “words [verba] a foot and a half long [sesquipedalia].” Horace clearly had a sense of humor.

pseudopseudohypoparathyroidism

We include pseudopseudohypoparathyroidism, another medical term, because this is one of the longest words to appear in major dictionaries that wasn’t created with length in mind. Pseudo- is a combining form meaning “false, pretended, unreal.”

You might notice the appearance of pseudo- twice. That’s because this disorder simulates the symptoms of pseudohypoparathyroidism, in which the body doesn’t respond to the parathyroid hormone. So, there are two levels of “faking it” going on here.

English isn’t the only language with lengthy elements of its lexicon. Get to know some of the world’s longest words!

antidisestablishmentarianism

Often, people will bust out antidisestablishmentarianism as the longest word they know and are actually able to say. This word has rarely been used and is only mentioned due to its ridiculous length. This word refers to opposition to withdrawing support from the Anglican Church as the state church of 19th-century England. 

supercalifragilisticexpialidocious

Even though the sound if it is something quite atrocious, we do really like the word supercalifragilisticexpialidocious. This nonsensical word with no real meaning was popularized by the 1964 Disney film Mary Poppins and is often used by children as an example of a humorously long word. Songwriters Richard and Robert Sherman take credit for this exact spelling of the word, but the word itself existed even before Mary Poppins made it popular. 

floccinaucinihilipilification

Here’s one that is also very meta: floccinaucinihilipilification is a rarely used word that means “the estimation of something as valueless.” It is usually used in reference to itself! Dating back to the 1700s, the word contains four Latin roots that all mean “of little value” or “trifling”: floccī, naucī, nihilī, and pilī.

honorificabilitudinitatibus

The word honorificabilitudinitatibus, which is said to mean “capable of receiving honor,” has two major honors to its name. Firstly, it is the longest word to ever appear in the works of William Shakespeare. Billy the Bard only ever used it once, in his play Love’s Labour’s Lost (1590s). Secondly, honorificabilitudinitatibus is the longest English word wherein the consonants and vowels alternate back and forth. Check it again if you didn’t notice! 

uncharacteristically

Uncharacteristically for most of the really long words you’ve seen so far, the word uncharacteristically is often said to be the longest word that the average English speaker will commonly see or actually use in everyday life. As you may already know, uncharacteristically is an adverb that describes something as not being typical or acting in a characteristic manner. 

incomprehensibilities

At 21 characters, another one of the longest words you might actually use yourself is incomprehensibilities. We define incomprehensible as “impossible to comprehend or understand,” so incomprehensibilities are “things you can’t comprehend.” ¿Comprendes?

uncopyrightables 

If you look closely at the spelling, you’ll notice a peculiar thing about this word with 16 letters. It does not repeat any letter; each character is used only once. This word is sometimes called an isogram among lovers of words and word games.

One of the longest isograms is subdermatoglyphic, at 17 characters. But, since subdermatoglyphic (dermatoglyphics studies the patterns of skin markings on the hands and feet) is a bit scientific and certainly not one that is used often, we’re spotlighting uncopyrightables instead because it’s one we can all remember. It means, of course, “items that are unable to be copyrighted.”

rhythms 

The word rhythms may not look like much at only seven letters long, but it is said to be the longest English word without one of the five main vowels in it. The letter Y, that wishy-washy “sometimes vowel,” is filling in while A, E, I, O, and U are taking a break. As we all know, the word rhythms means “movements or procedures with uniform or patterned recurrence of a beat, accent, or the like.” 

Are there really words without vowels? Depending on the definition, the answer might elicit a hmm.

strengths 

Strengths is another smaller word with a big achievement under its belt. It is the longest English word with only a single vowel in it. Considering it is only eight letters long, that really shows you how much we value our vowels. The plural strengths is most often used to mean “positive or valuable attributes or qualities.”  

squirrelled 

We go nuts for this word. While the word squirreled usually only has one L in American English, some dictionaries accept this British English version as an alternate spelling. Some Americans pronounce the word squirrelled as a one-syllable word (rhyming with “curled”). This makes squirrelled the longest one-syllable word in the English language at 11 letters. If all of that sounds too squirrely for you, the one-syllable verb broughammed from the noun brougham, a type of carriage, is also 11 letters long. 

As an aside, some may tell you that the word schtroumpfed is actually the longest “English” word with only a single syllable. This word has been used in some translations of The Smurfs (which is Les Schtroumpfs in French) in place of the more commonly used nonsensical verb smurfed. In our opinion, claiming schtroumpfed is the longest one-syllable word is just a bunch of smurf. 

Aegilops

Aegilops sounds like the name of a mythical monster, but it is actually the name of a genus of wild grasses commonly known as goatgrass. In addition to that, Aegilops is also commonly said to be the longest English word that has all of the letters in alphabetical order.

Conclusion

We would like to conclude that while the longest words mentioned above are not required by students, writers, or teachers to improve their vocabulary, knowing them is fun and increases mental horizons in English literature. It is also to be noted that this vocabulary will come in handy if you are having a conversation with a medical professional, an engineer, or a scientist who works in the fields to which these words are related.

According to the 20th volume of the Oxford English Dictionary, there are a total of 171,476 words in current use. With this number of words, your mind will begin to imagine which words are the longest and how many letters they have. Well, you needn’t wonder anymore, this article has got you covered.

A very high percentage of the longest words in English are medicine and chemistry terminologies. However, you will not find some of them in the dictionary as space is an essential constraint of a dictionary.

For example, the longest word in the English language is METHIONYLTHREONYLTHREONYGLUTAMINYLARGINYL…ISOLEUCINE which is the full chemical name for the human protein titin. The word has 189,819 letters, taking about three-and-a-half hours to pronounce. The problem with including chemical names in the dictionary is that there is no limit to how long it can be.

In the same light, the longest word to ever appear in the literature is from Assemblywomen, a play by Aristophanes published in 391 BC. LOPADOTEMACHOSELACHOGALEOKRANIOLEIPSAN…PTERYGON is a Greek word that has a total of 171 letters that translates to 183.

However, this article is focused on the longest English words in the dictionary. There are several lengthy words in the dictionary. Continue reading to appreciate a few of them.

This is the longest word in the dictionary, with a total of forty-five letters. Also, it has 19 syllables which divides as pneu-mo-no-ul-tra-mi-cro-scop-ic-sil-i-co-vol-ca-no-co-ni-o-sis.

The forty-five-letter word is a noun that refers to a lung disease caused by the inhalation of silica, quartz dust, very fine ash or sand dust found in volcanoes.

Pneumonoultramicroscopicsilicovolcanoconiosis was invented in the 1930s during the annual meeting of the National Puzzlers’ League (N.P.L.) by Everett M. Smith (the president). The word was coined in imitation of very long medical terms. The 45-letter word is a synonym for the disease known as silicosis.

Additionally, it first appeared in the supplement to the Merriam-Webster New International Dictionary in the year 1939.

The second position on the list is Hippopotomonstrosesquippedaliophobia, with a total of thirty-six letters. Plus, it has 15 syllables which divides into hip-po-pot-o-mon-stro-ses-quip-ped-al-i-o-pho-bi-a.

Hippopotomonstrosesquippedaliophobia is a noun that refers to the fear of long words. Isn’t it ironic that the word that means the fear of long words is actually one of the longest words in the dictionary?

Additionally, the prefix hippopoto- and monstro- which alludes to hippopotamus and monsters, were only added to the word to blow the word out of proportion. You don’t necessarily need them for the meaning. The word’s true meaning comes for the Latin word sesquipedalis, which means a foot and a half long and the word phobia, meaning an irrational fear.

Supercalifragilisticexpialidocious is the third-longest word in the English language, having a total of thirty-four letters. However, it is not a word that appears in all dictionary, only a few. Plus, it has 14 syllables which divides into su-per-cal-i-frag-i-lis-tic-ex-pi-al-i-do-cious.

The thirty-four-letter word is an adjective that means extraordinarily good or wonderful. However, the oxford dictionary defines the word as a nonsense word typically used by children to express excited approbation.

If you ever watched Mary Poppins (the 1964 film) as a child, you might remember supercalifragilisticexpialidocious as first used by Mary Poppins. Mary Poppins described it as a word to use when you have nothing to say.

This is the fourth-longest word in the dictionary, and the longest non-coined word in the English language with a total of thirty letters is pseudopseudohypoparathyroidism. The thirty-letter word has 11 syllables, which divide into Pseu-do-pseu-do-hy-po-pa-ra-thy-roid-ism.

Pseudopseudohypoparathyroidism, which is often abbreviated as PPHP, is a noun that refers to the condition that causes the soft tissues and joints in the body to harden, leading to a round face, short stature and short hand bones. This condition is often inherited

Pseudo means false or fake. The word consists of the word pseudo twice because the disorder stimulates the peculiar symptoms of pseudohypoparathyroidism, whereby the body does not respond to the parathyroid hormone. This shows two-level of faking it or falseness going on.

The fifth on the list is Floccinaucinihilipilification coming with a total of twenty-nine letters. Floccinaucinihilipilification has 12 syllables which divides into floc-ci-nau-ci-ni-hil-i-pil-i-fi-ca-tion.

Floccinaucinihilipilification is a noun that refers to the action or habit of estimating something as worthless or valueless. It is mostly never used except in a list of the longest words in the English language. However, when it is used, it is often in reference to itself.

The twenty-nine letter word dates back to the mid-18th century having Latin roots. It is made up of the Latin words flocci, nauci, nihili, and pili, which means little value. The first recorded use of Floccinaucinihilipilification was in a letter by William Shenstone in 1741.

Following closely on the list is Antidisestablishmentarianism, with a total of twenty-eight letters. Antidisestablishmentarianism is pronounced in 12 syllables which divides into an-ti-dis-es-tab-lish-ment-ar-i-an-is-m.

Antidisestablishmentarianism originally referred to the opposition of the Church of England’s disestablishment and the advocacy that the church should continue to receive government patronage. However, it is now being used to describe any opposition to withdrawing government support from religions or churches.

Also, in 1838, Antidisestablishmentarianism was first said by Weekley. The word was first recorded in Gladstone’s “Church and State. Furthermore, the twenty-eight-letter word, a prime example of a sesquipedalian word, is never really used today and was rarely used after it was formed.

Honorificabilitudinitatibus is the longest word in the dictionary that features only alternating consonants and vowels with 27 letters. Also, it has a total of 11 syllables, which divides into Hon-ori-fi-ca-bi-li-tu-dini-tat-i-bus.

Honorificabilitudinitatibus is a noun that means the state of being able to achieve honours. Also, it is the ablative and dative plural of the Latin word honorificabilitudinitas. The twenty-seven letters only appeared only once in Shakespeare’s works (Love’s Labour’s Lost).

Coming eighth on the list is incomprehensibilities with a total of twenty-one letters. The pronunciation of Incomprehensibilities comes in 8 syllables, which divides into in-com-pri-hen-si-bi-li-ties.

Incomprehensibilities is a noun that refers to the things that are impossible to understand or comprehend; it could also mean unintelligible.

The word was derived in Middle English from the Latin word incomprehēnsibilis; it was first recorded sometime in the early 1300s. Also, during the 1990s, the word was named the longest word in common usage.

With 20 letters words, the next letter is uncharacteristically. The pronunciation of the word comes in 8 syllables, which divides into un-char-ac-ter-is-ti-ca-lly.

Uncharacteristically, it is an adverb that means performing an action in a way that is not typical for a person or thing. The first known use of uncharacteristically was in 1748.

Isograms are words that have no repeated letters in their spellings; there are several isograms in the English dictionary. The longest isogram is subdermatoglyphic, with a total of 17 letters. However, subdermatoglyphic is not included in the dictionary; that is why it is not part of this list.

On the other hand, the next longest isogram is uncopyrightable, which is a word included in the English dictionary, has a total of 15 letters. Plus, it has six syllables that break down into un-co-py-righ-ta-ble.

Uncopyrightable is an adjective that means not allowed to or not able to be protected by copyright, the first known use of the word was in 1926.

For the long time, lexicographers have been debating about the legitimacy of certain words as possible entrants to the English dictionary. For me, the longer the word and the more the number of syllables in it, the more interesting it becomes. Find out some of the most exquisitely coined words in the English language from this article.

Longest word

Methionylthreonylthreonylglutaminylarginyl […] isoleucine
Here’s the deal: the world’s longest English word has exactly 189,819 letters in it and it takes 3 hours and 33 minutes to pronounce it completely!

Wondering what commands such an enormous (literally) honor? Well, it is the chemical name of the world’s largest known protein called titin or connectin. It is made up of 244 individually folded protein domains which in turn are connected by unstructured peptide sequences (largest known polypeptide containing 34,350 amino acids in the human body). Fascinating as the name of this wonder is, there exists some debate as to whether this technical term can actually be considered a word. But even then, mesmerizing it is, isn’t it? And guess what? Here in this article, you will actually get to see this ginormous word if you read on.

But even otherwise, the English language is a huge storehouse of long words that I find rather satisfying to pronounce. They are grand tongue twisters that make perfect sense. Two of my favorite words for the longest time have been inconsequential and quintessentially. I am psychologically satiated to the hilt every time I utter them and utter them a lot I do. But there are other words that are very rarely used and even more rarely heard of. Let’s check some of them out below. If you love the language and lap up trivia like there’s no tomorrow, this is a train ride you should definitely not miss.
