In any language it is impossible to imagine a word without a root. There are also words that consist only of the root: boron, house, stake. Other morphemes have an auxiliary, complementary function, and only at the root is meaning.
A root in linguistics is a part of a word or morpheme that contains the meaning of a word, its conceptual kernel. Other morphemes (suffixes, prefixes, endings) have no independent meaning. They only add additional shades to the main meaning. Anyone who speaks Russian will understand perfectly well that the «tail» is not at all the same as the «tail», but in both cases it is about the same part of the animal’s body, because these words have a common root.
Single-root words
All words that have the same root are called same root. They can belong both to one part of speech (cat — cat — cat — cat), and to different (start — start — start).
Difficult words
There is always one root in the word. But there are words with two roots. Such words are called difficult. So, the word «pedestrian» has two roots: «pedestrian» and «move».
Homonymous roots
There are words whose roots are spelled the same, but they have different meanings. These are the roots of homonyms — words that are the same in spelling, but different in meaning: the words «key» in the meaning of «source» and «key» in the meaning of «device for opening the door, master key» are written in the same way, but the word «key» in the first meaning a single-root word will be, for example, «key (water)», and in the second meaning — «key-keeper».
Alternating sounds at the root
It happens that vowels or consonants in the same root are written differently in different words of the same root, alternating, for example, «run — run» or «put — adjective». The rules help to understand exactly how the root is spelled in a particular word. Sometimes it depends on whether the vowel is under stress, or not (tan — tanned), sometimes on which letter the root ends with (grew — grown), sometimes on the meaning of the word, for example, dip (immerse in liquid) and get wet (soak with moisture) … The alternation of sounds is due to historical processes occurring in the language (historical alternation) or pronunciation features (phonetic alternation).
Splicing roots
As a result of changes in the language, some roots «merged» with prefixes, suffixes. In such words, one can distinguish the historical (etymological) root and the modern, accepted in the language at the moment. So, in the word «factory» the etymological root of «waters», modern — «plant». Such roots are called linked. The roots of modern words that coincide with etymological ones are called free — there are most of them in the Russian language.

From Wikipedia, the free encyclopedia
A root (or root word) is the core of a word that is irreducible into more meaningful elements.[1] In morphology, a root is a morphologically simple unit which can be left bare or to which a prefix or a suffix can attach.[2][3] The root word is the primary lexical unit of a word, and of a word family (this root is then called the base word), which carries aspects of semantic content and cannot be reduced into smaller constituents.
Content words in nearly all languages contain, and may consist only of, root morphemes. However, sometimes the term «root» is also used to describe the word without its inflectional endings, but with its lexical endings in place. For example, chatters has the inflectional root or lemma chatter, but the lexical root chat. Inflectional roots are often called stems, and a root in the stricter sense, a root morpheme, may be thought of as a monomorphemic stem.
The traditional definition allows roots to be either free morphemes or bound morphemes. Root morphemes are the building blocks for affixation and compounds. However, in polysynthetic languages with very high levels of inflectional morphology, the term «root» is generally synonymous with «free morpheme». Many such languages have a very restricted number of morphemes that can stand alone as a word: Yup’ik, for instance, has no more than two thousand.
The root is conventionally indicated using the mathematical symbol √; for instance, the Sanskrit root «√bhū-» means the root «bhū-«.
Examples[edit]
The root of a word is a unit of meaning (morpheme) and, as such, it is an abstraction, though it can usually be represented alphabetically as a word. For example, it can be said that the root of the English verb form running is run, or the root of the Spanish superlative adjective amplísimo is ampli-, since those words are derived from the root forms by simple suffixes that do not alter the roots in any way. In particular, English has very little inflection and a tendency to have words that are identical to their roots. But more complicated inflection, as well as other processes, can obscure the root; for example, the root of mice is mouse (still a valid word), and the root of interrupt is, arguably, rupt, which is not a word in English and only appears in derivational forms (such as disrupt, corrupt, rupture, etc.). The root rupt can be written as if it were a word, but it is not.
This distinction between the word as a unit of speech and the root as a unit of meaning is even more important in the case of languages where roots have many different forms when used in actual words, as is the case in Semitic languages. In these, roots (semitic roots) are formed by consonants alone, and speakers elaborate different words (belonging potentially to different parts of speech) from the root by inserting different vowels. For example, in Hebrew, the root ג-ד-ל g-d-l represents the idea of largeness, and from it we have gadol and gdola (masculine and feminine forms of the adjective «big»), gadal «he grew», higdil «he magnified» and magdelet «magnifier», along with many other words such as godel «size» and migdal «tower».
Roots and reconstructed roots can become the tools of etymology.[4]
Secondary roots[edit]
Secondary roots are roots with changes in them, producing a new word with a slightly different meaning. In English, a rough equivalent would be to see conductor as a secondary root formed from the root to conduct. In abjad languages, the most familiar of which are Arabic and Hebrew, in which families of secondary roots are fundamental to the language, secondary roots are created by changes in the roots’ vowels, by adding or removing the long vowels a, i, u, e and o. (Notice that Arabic does not have the vowels e and o.) In addition, secondary roots can be created by prefixing (m−, t−), infixing (−t−), or suffixing (−i, and several others). There is no rule in these languages on how many secondary roots can be derived from a single root; some roots have few, but other roots have many, not all of which are necessarily in current use.
Consider the Arabic language:
- مركز [mrkz] or [markaza] meaning ‘centralized (masculine, singular)’, from [markaz] ‘centre’, from [rakaza] ‘plant into the earth, stick up (a lance)’ ( ر-ك-ز | r-k-z). This in turn has derived words مركزي [markaziy], meaning ‘central’, مركزية [markaziy:ah], meaning ‘centralism’ or ‘centralization’, and لامركزية, [la:markaziy:ah] ‘decentralization’[5]
- أرجح [rjh] or [ta’arjaħa] meaning ‘oscillated (masculine, singular)’, from [‘urju:ħa] ‘swing (n)’, from [rajaħa] ‘weighed down, preponderated (masculine, singular)’ ( ر-ج-ح | r-j-ħ).
- محور [mhwr] or [tamaħwara] meaning ‘centred, focused (masculine, singular)’, from [mihwar] meaning ‘axis’, from [ħa:ra] ‘turned (masculine, singular)’ (ح-و-ر | h-w-r).
- مسخر [msxr], تمسخر [tamasxara] meaning ‘mocked, made fun (masculine, singular)’, from مسخرة [masxara] meaning ‘mockery’, from سخر [saxira] ‘mocked (masculine, singular)’ (derived from س-خ-ر[s-x-r]).»[6] Similar cases may be found in other Semitic languages such as Hebrew, Syriac, Aramaic, Maltese language and to a lesser extent Amharic.
Similar cases occur in Hebrew, for example Israeli Hebrew מ-ק-מ √m-q-m ‘locate’, which derives from Biblical Hebrew מקום måqom ‘place’, whose root is ק-ו-מ √q-w-m ‘stand’. A recent example introduced by the Academy of the Hebrew Language is מדרוג midrúg ‘rating’, from מדרג midrág, whose root is ד-ר-ג √d-r-g ‘grade’.»[6]
According to Ghil’ad Zuckermann, «this process is morphologically similar to the production of frequentative (iterative) verbs in Latin, for example:
- iactito ‘to toss about’ derives from iacto ‘to boast of, keep bringing up, harass, disturb, throw, cast, fling away’, which in turn derives from iacio ‘to throw, cast’ (from its past participle iactum).[6]
Consider also Rabbinic Hebrew ת-ר-מ √t-r-m ‘donate, contribute’ (Mishnah: T’rumoth 1:2: ‘separate priestly dues’), which derives from Biblical Hebrew תרומה t’rūmå ‘contribution’, whose root is ר-ו-מ √r-w-m ‘raise’; cf. Rabbinic Hebrew ת-ר-ע √t-r-‘ ‘sound the trumpet, blow the horn’, from Biblical Hebrew תרועה t’rū`å ‘shout, cry, loud sound, trumpet-call’, in turn from ר-ו-ע √r-w-`.»[6]
and it describes the suffix.
Category-neutral roots[edit]
Decompositional generative frameworks suggest that roots hold little grammatical information and can be considered «category-neutral».[7] Category-neutral roots are roots without any inherent lexical category but with some conceptual content that becomes evident depending on the syntactic environment.[7] The ways in which these roots gain lexical category are discussed in Distributed Morphology and the Exoskeletal Model.
Theories adopting a category-neutral approach have not, as of 2020, reached a consensus about whether these roots contain a semantic type but no argument structure,[8] neither semantic type nor argument structure,[9] or both semantic type and argument structure.[10]
In support of the category-neutral approach, data from English indicates that the same underlying root appears as a noun and a verb — with or without overt morphology.[7]

English Examples — Overt[7]
Root Noun Verb advertise an advertisement to advertise character a character to characterize employ an employment to employ alphabet an alphabet to alphabetize -
English Examples — Covert[7]
Root Noun Verb dance a dance to dance walk a walk to walk chair a chair to chair wardrobe a wardrobe to wardrobe
In Hebrew, the majority of roots consist of segmental consonants √CCC. Arad (2003) describes that the consonantal root is turned into a word due to pattern morphology. Thereby, the root is turned into a verb when put into a verbal environment where the head bears the «v» feature (the pattern).[11]
Consider the root √š-m-n (ש-מ-נ).
| Pattern | Pronounced word | Gloss |
|---|---|---|
| CeCeC (n) | šemen | oil, grease |
| CaCCeCet (n) | šamenet | cream |
| CuCaC (n) | šuman | fat |
| CaCeC (adj) | šamen | fat |
| hiCCiC (v) | hišmin | grow fat/fatten |
| CiCCeC (n) | šimen | grease |
Although all words vary semantically, the general meaning of a greasy, fatty material can be attributed to the root.
Furthermore, Arad states that there are two types of languages in terms of root interpretation. In languages like English, the root is assigned one interpretation whereas in languages like Hebrew, the root can form multiple interpretations depending on its environment. This occurrence suggests a difference in language acquisition between these two languages. English speakers would need to learn two roots in order to understand two different words whereas Hebrew speakers would learn one root for two or more words.[11]
| English Root | English Word | Hebrew Root | Hebrew Word | Gloss |
|---|---|---|---|---|
| √CREAM | cream | √š-m-n ש-מ-נ | šamenet | ‘cream’ |
| √FAT | fat | √š-m-n ש-מ-נ | šuman | ‘fat’ |
Alexiadou and Lohndal (2017) advance the claim that languages have a typological scale when it comes to roots and their meanings and state that Greek lies in between Hebrew and English.[12]

Morphemica is one of the most difficult topics for a child. Correctly divide the word into parts can not every schoolboy. Nevertheless, the ability to correctly identify parts of the word is a necessary condition for the assimilation of a number of rules of Russian spelling.
Russian language: what is the root of the word
Morpheme is a significant part of the word. First, with the morphemic analysis, the foundation and the ending are distinguished. The basis is the immutable part of the word, and the ending is the variable and pointing to the form of the word. For example, in the word «cows» cows — this is the basis, and you — this is the ending. The basis of the word includes the following parts of the word (morpheme) — prefix, root, ending. An important morpheme, denoted by an arc, is the root of the word.
What is the root of the word? The root of the word is a common part of the related words. What words are called crocheted? The root of one root is one root, while the other morphemes are different. For example, high — height, leaf — foliage, daddy — daddy, sister — sister.
How to find root words
- There are words with the same roots, but notwhich are crooked. So, in the adjectives «peaceful» and «world» one can single out the root-world, but words will not be single-root, since in the first case the adjective is formed from the word «peace» in the meaning «without war», and in the second — in the meaning » what is around, the universe. » Lexical differences of words can not make words self-root.
- You should not mix root words and forms of one word. For example, the words «carrots» and «carrots» are single-root words, and «carrots» and «carrots» are word forms of the word «carrot».
- Raw words do not necessarily belong toone part of speech. So, if «carrots» and «carrots» are nouns, then «run» and «run» are a noun and a verb, and «fun» and «hilarious» are an adverb and an adjective.
- Do not forget that apart from the root, there is a word in the wordprefixes and suffixes. If you can select them, then finding the root words will be much easier. For example, the word «chin». In it, you can select the prefix of sub-, suffix -ok and root -brod-. So, now you can pick up the root words: bearded, beard, beardless.
- Difficulties can arise because of historicalalternating consonants. Outwardly, the roots are different, but the meaning is preserved. The fact is that earlier the sound of Russian speech was different from what one can hear today. Due to historical changes in the sound structure of the language, the same root in different words may sound different.
Some examples:
- to-h «: hands / a — hand» / k / a
- k-u-h «: n» uh / — n «u / o — n» u «/ n / w
- Ms.: legs / a — knife / c / a
- Mrs.-z: friend / — friends / and / «- friends» / ya
- x-w: yx / o-yw / u
Although the final consonants in the roots differ, the presented pairs of words are single-root.
What is a root orthogram?
Why do we need to highlight the root of the word and look forroot words? The fact is that one of the basic principles of Russian orthography (spelling) is a morphemic principle. It is manifested, for example, in the rule «The Uncorrected Vowel at the Root of the Word» or in the rule «Unpronounceable Consonant in the Root of the Word».
In the first case, it is necessary to find such a single root word, so that the verified vowel is under stress. For example, in_water — water, с_стра — sister, д_ловой — business.
In the second case, it is necessary to find a word such that an unpronounceable consonant is well audible. For example, it’s an honor, a crunch, a crunch.
Not only in these cases is it worth remembering what the root of the word is. Another important rule is based on the ability to allocate a root.
Alternating vowels in the root
Because of the same historical reasons in someroot words are written different vowels. For example, in the roots with alternating vowels e-u (-ber- -bir-, -per-pir-, -mer- — world-, -style -style, -der -dir, etc.), the letter «u «is written only when the root suffix -a- follows, for example: die — die, spread — spread, tear — razdert, shine — shine.
The alternating roots are also:
lag-lodges, kas-kos, floating-pilov, clan-clone, creature creature, mac-mok, har-mountains, zarzor, skach-scoch, equal-level, rastro-rasch.

A basic word to which affixes (prefixes and suffixes) are added is called a root word because it forms the basis of a new word. The root word is also a word in its own right. For example, the word lovely consists of the word love and the suffix -ly.
Besides, What’s a root word example?
What Is a Root Word? A root word is a word or word part that forms the basis of new words through the addition of prefixes and suffixes. … For example, “egotist” has a root word of “ego” plus the suffix -ist. “Acting” has the root word “act” and -ing is merely the suffix.
Keeping this in mind, How do you find the root of a word? A root word is a basic word with no prefix or suffix added to it (a prefix is a string of letters that go at the start of a word; a suffix is a string of letters that go at the end of a word). By adding prefixes and suffixes to a root word we can change its meaning.

What is the full meaning of basic?
BASIC (Beginners’ All-purpose Symbolic Instruction Code) is a family of general-purpose, high-level programming languages whose design philosophy emphasizes ease of use.
A reader asks about the terms prefix, root, and suffix, and wonders how to distinguish them in a word.
At the most basic level, words are made up of units of meaning called morphemes. A morpheme may be a recognizable word like tree, run, or button that cannot be broken down into smaller meaningful parts.
A morpheme can represent meaning without being a word. For example, the prefix un- expresses the idea of negation. The suffix -ness, used to turn adjectives into abstract nouns, is a morpheme. The root struct, seen in structure and construct, is a morpheme that embodies the meaning of “to build,” but it cannot stand alone as an English word.
A root is a word’s basic part and carries its fundamental meaning. In the word sadness, for example, the root is sad. Sometimes two roots combine to make one word, as in telephone, a combination of the morpheme tele, which relates to distance, and the morpheme phone, which relates to sound.
Prefixes and suffixes belong to a set of morphemes called affixes. An affix is an element added to the base form or stem of a word to modify its meaning.
Standard English makes use of two types of affix: prefixes and suffixes. A prefix is added at the beginning of a word. For example, the prefix re- is added to a root or a word to denote the idea of doing it again: return, renew, reconstruct.
A suffix is added at the end of a word.
Suffixes are of two kinds, derivational and inflectional. A derivational suffix changes the underlying meaning of the word; an inflectional suffix changes the tense of a verb or the number of a noun, or performs some other grammatical purpose.
Some common derivational suffixes are, -er, -al, -ful, and -ize. The suffix -er added to a verb creates a person or object that performs the action of the verb: teach/teacher, walk/walker, kill/killer, compute/computer; -al and -ful change nouns into adjectives: accident/accidental, forget/forgetful; -ize changes a noun into a verb: terror/terrorize.
Common inflectional suffixes are endings such as, –ed, -ly, -‘s, -s, -er, -ed, -es, -est, and -ing.
Derivational endings are added to a root. For example, the word reconstruction is made up of the root struct, two prefixes, re- and con-, and a suffix, tion. (Because struct ends in t and tion begins with t, one of the ts had to go.)
Inflectional endings are added to a stem, which is the entire word that the ending is being added to. In the words reconstructed and reconstructing, for example, the stem is reconstruct-.
