Definition
- Noun:
- A minimal unit in the lexicon of a language: A lexeme is an abstract unit of meaning that encompasses all the different grammatical forms a word can take. It is the fundamental, dictionary-entry form of a word, distinct from its specific inflected or derived variants.
Usage
- A lexeme is the core concept behind related word forms. For example, the words "run," "runs," "ran," and "running" are all different surface forms that belong to the single English lexeme .
- In linguistic analysis, lexemes are the basic building blocks of a language's vocabulary (lexicon). Identifying lexemes helps in understanding how words are related and how meaning is structured.
Examples
- The forms "happy," "happier," and "happiest" are all part of the same lexeme, .
- The words "sing," "sings," "sang," "sung," and "singing" are considered different realizations of the single lexeme .
- In the dictionary, you look up the lexeme "go," not each of its forms like "went" or "going."
Advanced Usage
- Lexeme vs. Word Form: A "word form" is the specific shape a word takes in a given context (e.g., "books"). The "lexeme" is the abstract set that includes all such forms (e.g., ).
- Lexeme and Lemma: The "lemma" is the canonical form, or headword, used to represent a lexeme in a dictionary (e.g., "be" for the lexeme that includes "am, is, are, was, were, been, being").
