Lemmaform
Lemmaform refers to the canonical dictionary form of a word, used as the base citation form in dictionaries, corpora, and natural language processing. It represents the lemma, the form under which a word is listed in a lexicon, and is typically inflectionally invariant, in that it remains constant across different grammatical forms. Inflected variants such as running, runs, or ran carry tense, number, or other grammatical information that the lemmaform abstracts away for reference and indexing.
In practice, lemmaforms are produced by lemmatization, a process that combines morphological analysis with often part-of-speech
Examples: English: running -> run; children -> child; went -> go. French: mange -> manger. In highly inflected languages such
Uses and challenges: Lemmaforms are used in indexing, search, and text normalization, aiding cross-form matching in
