Lexis (linguistics)

All the words in a language collectively

In linguistics, the term lexis (from Ancient Greek: λέξις 'word') designates the complete set of all possible words in a language, or a particular subset of words that are grouped by some specific linguistic criteria. For example, the general term English lexis refers to all words of the English language, while more specific term English religious lexis refers to a particular subset within English lexis, encompassing only words that are semantically related to the religious sphere of life. In systemic-functional linguistics, a lexis or lexical item is the way one calls a particular thing or a type of phenomenon.
