the meaning of a word that is inherent only in a given lexical unit, as opposed to the grammatical meaning of whole classes and categories of words. The lexical content of most autonomous lexemes is heterogeneous and represents a sense structure, a hierarchical collateral subordination of the individual meanings, or from another standpoint, the lexical-semantic variants of a word. This organizational property of lexical semantics is called polysemy, or the semantic variation of a word. Depending on the object and notional relationship of a word, meanings can be literal and metaphorical; depending on the degree of contextual conditionality, meanings can be free, phraseologically bound, or constructively conditioned.
