But most of all HAVE FUN!!!

Ready to take your Scrabble skills to the next level? This list of the longest words in the English language could score you major points on your next game — if you can remember how to spell them.

Some of the words that qualify for the title take hours to pronounce, like the 189,819-letter word for the  protein Titin. Additionally, many of the longest words are medical terms, so we have excluded some of them to allow for more variety. The end result is a list of fascinatingly lengthy words that will make your vocabulary downright sesquipedalian.

Antidisestablishmentarianism

Part of Speech: noun

Definition: opposition to the disestablishment of the Church of England

Origins: While the word originated in 19th century Britain, it is now used to refer to any opposition to a government withdrawing support from a religious organization. Though rarely used in casual conversation, the word was featured in the Duke Ellington song, “You’re Just an Old Antidisestablishmentarianist.”  

Floccinaucinihilipilification

Part of Speech: noun

Definition: the act of defining or estimating something as worthless

Origins: This word stems from the combination of four Latin words, all of which signify that something has little value: flocci, nauci, nihili, pilifi. This style of word creation was popular in Britain in the 1700s. 

Pneumonoultramicroscopicsilicovolcanoconiosis

Part of Speech: noun

Definition: an invented word said to mean a lung disease caused by inhaling a fine dust

Origins: This word emerged in the late 1930s, and was said to be invented by Everett K. Smith, president of the National Puzzlers’ League, in an imitation of very long medical terms. It is not found in real medical usage.

Pseudopseudohypoparathyroidism

Part of Speech: noun

Definition: an inherited disorder similar to pseudohypoparathyroidism

Origins: This genetic disorder causes “short stature, round face and short hand bones,” according to the National Institutes of Health. Despite having a similar name, it is not the same as pseudohypoparathyroidism.

Psychoneuroendocrinological

Part of Speech: adjective

Definition: of or related to to the branch of science concerned with the relationships between psychology, the nervous system, and the endocrine system 

Origins: This term was first seen in the 1970s in Journal of Neurological Science, a medical journal. 

Sesquipedalian

Part of Speech: adjective

Definition: having many syllables or characterized by the use of long words

Origins: The Roman poet Horace used this term to caution young poets against relying on words that used a large number of letters. It was adopted in the 17th century by poets to ridicule their peers who used lengthy words.

Hippopotomonstrosesquippedaliophobia

Part of Speech: noun

Definition: fear of long words

Fun Fact: This word is most often used in humorous contexts. It is an extension of the word sesquipedalophobia, which has the same meaning and is more often used in a formal context.  

Incomprehensibilities

Part of Speech: noun

Definition: things that are impossible to understand or comprehend

Fun Fact: In the 1990s, this word was named the longest word in common usage.

Uncopyrightable

Part of Speech: adjective

Definition: not able or allowed to be protected by copyright

Fun Fact: This word is one of the longest isograms (a word that does not repeat letters) in the English language.

Dermatoglyphics

Part of Speech: noun

Definition: the scientific study of hands, including fingerprints, lines, mounts, and shapes

Fun Fact: Unlike palmistry, this study is based in science and is often used in criminology as a way to identify both perpetrators and victims.

Euouae

Part of Speech: noun

Definition: a type of cadence in medieval music

Fun Fact: While this word might not look as impressive as others on this list, it’s the longest word in the English language to be composed entirely of vowels. (It’s also the word with the longest string of vowels.)

Psychophysicotherapeutics

Part of Speech: noun

Definition: a therapeutic approach that integrates both the mind and body

Fun Fact: While the Oxford Dictionary does not provide an official definition of this word, it is included on their list of the longest words in the English language. 

Otorhinolaryngological

Part of Speech: adjective

Definition: of or relating to the medical specialization involving the ear, nose, and throat

Fun Fact: This medical specialization is more commonly known by its acronym, ENT. 

The Longest Words in English

websters second international dictionary

Most English words longer than about 15-20 letters are scientific, meaningless, or highly specialized, and they tend to be formed by affixation. This is the act or process of adding affixes to a base word to produce a derivative word—in the word affixation, for instance, -ation is an affix. Here are some of the longest words.

respiratory masks

The longest word entered in most standard English dictionaries is Pneumonoultramicroscopicsilicovolcanoconiosis with 45 letters. Our definition is «a lung disease caused by inhalation of very fine silicate or quartz dust.» The entry for this word can be found in our Medical Dictionary.

woman using microscope

Yes, that number is correct. The longest string of letters used to describe something isn’t technically a word—it’s the chemical name for a protein, begins with methionylthreonylthreonylglutaminyl…, and continues for quite a while after that. The name has 189,819 letters, fills more than 50 pages, and takes more than three hours to say. If you’ve got three hours to blow, you can listen to it said here.

28, 29, and 34 Letters

floating umbrella

There are some long words that are rarely or never used in a sentence, but instead are simply used as examples of long words, and for that reason we don’t include them in our dictionaries. The most famous of these are antidisestablishmentarianism, which has 28 letters and supercalifragilisticexpialidocious, which has 34 letters. Floccinaucinihilipilification (29 letters) («the act or habit of assessing something as worthless») is another of this ilk. Our claim is not that these aren’t words, but that they aren’t words that meet our criteria for entry. We explain why here.

lake

The longest place name in the United States is possibly a lake in Massachusetts called Lake Chargoggagoggmanchauggauggagoggchaubunagungamaugg (49 letters, or 53, if you count the Lake portion). It is also sometimes called Webster Lake. While the longer name is based on earlier names for the lake from the language of the Nipmuc people who inhabited the area, this version of the name—along with its reputed translation, «You fish on your side; I fish on my side; nobody fishes in the middle”—appears to have been the invention of a local newspaper editor.

alt-62a77ae9ab3cd

Photo: Hill near Hawkes Bay, NZ

The longest place name in the English-speaking world is thought to be a 1,001-foot-high hill in New Zealand called Taumatawhakatangihangakoauauotamateaturipukakapikimaungahoronukupokaiwhenu-akitanatahu. Similar to the lake mentioned above, this place name also has spelling variations. It comes from the Maori language and has been translated as “the place where Tamatea, the man who had big knees, the climber of mountains, the slider, the land-swallower that traveled about, played the nose flute that he had to the loved ones.” The hill is sometimes called “Taumata” for short.

30 Letters

medical test results

29 Letters

mdma pills in baggie

Methylenedioxymethamphetamine refers to a synthetic amphetamine used illicitly for its mood-enhancing and hallucinogenic properties. You may know this drug by another, shorter, name: ecstasy. Or you may know it by an even shorter name: MDMA. (Fun fact: in the 1970’s psychiatrists used it to «enhance» therapy sessions.)

23, 24, 25, 26, and 27 Letters

electroencephalograph

22 Letters

doctor examining ear

Counterrevolutionaries refers to people who participate in a revolution directed toward overthrowing a government or social system established by a previous revolution.

Deinstitutionalization refers to the release of institutionalized individuals from institutional care (as in a psychiatric hospital) to care in the community, and also to the reform or modification of an institution to remove or disguise its institutional character..

Otorhinolaryngological refers to a medical specialty concerned especially with the ear, nose, and throat and related parts of the head and neck.

21 Letters

confused child

Incomprehensibilities refers to things that are hard to comprehend or understand. (We’re pretty sure most of these words qualify.)

Pseudohermaphroditism refers to the condition of having the gonads and karyotype of one sex and external genitalia that is of the other sex or is ambiguous.

And finally, psychoneuroimmunology refers to a branch of medicine that deals with the influence of emotional states and nervous system activities on immune function.

(Did you count only 20 words in the list? The 21st is hippopotomonstrosesquippedaliophobia, which is fear of long words. Apologies to anyone who suffers from this condition with its 36-letter name—we’re sure we’ve made it worse.)

Longest Word in English: Pneumonoultramicroscopicsilicovolcanoconiosis

Letters: 45

Definition (noun): Lung disease caused by breathing in dust or volcanic ash

The patient is experiencing signs of pneumonoultramicroscopicsilicovolcanoconiosis after hiking near the site of a volcanic eruption.

This is the longest word that exists in the English language. As with other long words, you should be patient and break it down into its individual components.

As you can see below, knowing the parts of this word will be especially helpful for anyone studying English in an academic, scientific or medical environment.

Essential word parts: Pneumo- (lung), microscopic- (small), coni- (particles) and a suffix: -osis (often indicates a disease).

More Long Words in English

longest word in english

We will show you the essential parts of these long words that can help you learn the word itself and other English words. We will specifically note common English prefixes and suffixes to pay attention to.

Methionylthreonylthreonylglutaminylalanyl…isoleucine

Letters: 189,819

Definition (noun): Chemical composition of “titin,” which is the largest known protein in the body  

This word has taken some people around 2-3.5 hours to pronounce! Amazing, isn’t it? It’s not, however, considered the longest word in English—because it’s not in a dictionary. 

Essential word parts: Amino acid residues that make up the protein. These include methionine, threonine, glutamine, alanine, and isoleucine.

Floccinaucinihilipilification

Letters: 29

Definition (noun): Deciding that something has no value

Since my wallet was becoming so huge, I took a few minutes for some floccinaucinihilipilification of all the old cards I was keeping in there.

Essential word part: Nihili- (nothing)

Incomprehensibility

Letters: 19

Definition (noun): Impossible to understand

The incomprehensibility of the word made people question its meaning.

This word has common prefixes and suffixes that you will see in many other English words. Plus, you may already be familiar with more basic forms of this word, such as incomprehensible (adjective — impossible to understand)

Essential word parts: include a prefix in- (not), a root word prehend (from the Latin for “grasp”), and a suffix: –ity (suffix used to form a noun out of an adjective).

Supercalifragilisticexpialidocious

Subdermatoglyphic

Letters: 17

Definition (adjective): Pertaining to the layer of the skin beneath the fingertips

Hippopotomonstrosesquipedaliophobia

How to Learn the Longest Words in English

longest word in english

Firstly: Break each word down into manageable parts

While long English words can seem complex, breaking them down into parts will make learning them easier!

Each of the words we discuss in this article, we will show you the important elements including prefixes, suffixes and roots. Let’s define the parts of a word and what they represent.

  • Root word: the base form of a word
  • Prefix: an element attached to the beginning of a root word that alters its meaning
  • Suffix: an element attached to the end of a root word that alters its meaning

Secondly: Use vocabulary memory tricks

  • Put the words and word parts onto flashcards. Flashcards are a perfect way to study and memorize long words. The language learning program FluentU allows you to make your own multimedia flashcards which are connected to a curated library of authentic videos—including news reports, inspiring talks and music videos. 

  • Keep a running list. Track word components in a notebook. Any time you encounter a new prefix, suffix or root word, write it down in your list. This will help you keep track of the word parts you learn. You can refer to this list as you try to learn other long and complex words.

But most importantly, try to have fun with these words. Be patient and you will start pronouncing them in no time!

List of Long Words and their Meanings

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.
