Root (linguistics)
A root (also known as a root word or radical) is the core of a word that is irreducible into more meaningful elements. In morphology, a root is a morphologically simple unit which can be left bare or to which a prefix or a suffix can attach. 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. A root, or a root morpheme, in the stricter sense, is a mono-morphemic stem. An etymon is the root word in a proto-language from which the descendant forms arose.
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 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.
Roots are sometimes notated using the radical symbol ⟨√⟩ to avoid potential conflation with other objects of analysis with similar spellings or pronunciation: for instance, √bhū- specifically denotes the Sanskrit root bhū-.
English verb form running contains the root run. The Spanish superlative adjective amplísimo contains the root ampli-. In the former case, the root can occur on its own freely. In the latter, modification via affixation is required to be used as a free form. English has minimal use of morphological strategies such as affixation and features a tendency to have words that are identical to their roots. However, such forms as in Spanish exist in English such as interrupt, which may arguably contain the root -rupt, which only appears in other related prefixed forms (such as disrupt, corrupt, rupture, etc.). The form -rupt cannot occur on its own.
Examples of consonantal roots, which are related but distinct to the concept developed here, are formed prototypically by three (as few as two and as many as five) consonants. Speakers may derive and develop new words (morphosyntactically distinct, i.e. with different parts of speech) by using non-concatenative morphological strategies: inserting different vowels. Unlike 'root' here, these cannot occur on their own without modification; as such these are never actually observed in speech and may be termed 'abstract'. For example, in Hebrew, the forms derived from the abstract consonantal roots, a major Hebrew phonetics concept ג-ד-ל (g-d-l) related to ideas of largeness: 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.
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 a conductor as a secondary root formed from the root to conduct. In abjad languages, the most familiar 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 others have many, not all of which are necessarily in current use.
