Linguistics

• Inflection

  Inflection is the morphological process by which a single lexeme takes on different surface forms to express grammatical categories such as tense, number, and case — the variation that lemmatisation is designed to undo.

• Morphological Analysis

  Morphological analysis decomposes words into their constituent morphemes — stems, prefixes, suffixes, and inflectional endings — enabling NLP systems to recognise that surface-form variants refer to the same underlying concept.

• Suffix

  A suffix is a bound morpheme appended to the right end of a word stem, encoding grammatical properties or creating new words — and the primary target of every English stemming algorithm.
