From Latin lexis, from Ancient Greek λέξις (léxis, “word”) + -eme a suffix indicating a fundamental unit in some aspect of linguistic structure. Extracted from phoneme, from Ancient Greek φώνημα (phṓnēma, “sound”), from φωνέω (phōnéō, “to sound”), from φωνή (phōnḗ, “sound”).
lexeme (plural lexemes)
- (linguistics) Roughly, the set of inflected forms taken by a single word, such as the lexeme RUN including as members "run" (lemma), "running" (inflected form), or "ran", and excluding "runner" (derived term).
- (computing) an individual instance of a continuous character sequence without spaces, used in lexical analysis (see token)
- Ran, run, runs, and running are variations of the English lexeme run; whereas runner and runners aren’t: they are forms of the lexeme runner.
- Both hypodermic and dermatologist contain the morpheme derm, which is a root form referring to “skin”. This is not a lexeme, though.
