In linguistics, a word stem is a part of a word responsible for its lexical meaning. Typically, a stem remains unmodified during inflection with few exceptions due to apophony (for example in Polish, miast-o ("city") and w mieść-e ("in the city"); in English, sing, sang, and sung, where it can be modified according to morphological rules or peculiarities, such as sandhi).
A root, or a root morpheme, in the stricter sense, a mono-morphemic stem. The traditional definition allows roots to be either free morphemes or bound morphemes . Root morphemes are the building blocks for affixation and compounds .
In linguistic morphology and information retrieval, stemming is the process of reducing inflected (or sometimes derived) words to their word stem, base or root form—generally a written word form. The stem need not be identical to the morphological root of the word; it is usually sufficient that related words map to the same stem, even if this ...
The stem is the part of the word that never changes even when morphologically inflected; a lemma is the least marked form of the word. In linguistic analysis, the stem is defined more generally as a form without any of its possible inflectional morphemes (but including derivational morphemes and may contain multiple roots). [3]
G-Stem is the base stem, from the German Grund ("ground") D-Stem typically has a Doubled second root letter; L-Stem typically Lengthens the first vowel; N-Stem has a prefix with N; C- or Š-Stem often has a Causative meaning and has a prefix with Š (ʃ pronounced like English sh), S, H, or ʔ (the glottal stop).
Some noun stems like *h₂egʷn-o-'lamb', however, do not derive from known verbal roots. [7] In any case, the meaning of a noun is given by its stem, whether this is composed of a root plus a suffix or not. This leaves the ending, which conveys case and number. [8] Adjectives are also derived by suffixation of (usually verbal) roots.
In linguistics, morphology is the study of words, including the principles by which they are formed, and how they relate to one another within a language. [1] [2] Most approaches to morphology investigate the structure of words in terms of morphemes, which are the smallest units in a language with some independent meaning.
The word etymology is derived from the Ancient Greek word ἐτυμολογία (etumologíā), itself from ἔτυμον (étumon), meaning ' true sense or sense of a truth ', and the suffix -logia, denoting ' the study or logic of '. [3] [4] The etymon refers to the predicate (i.e. stem [5] or root [6]) from which a
