The study of meaning in language

Lexical semantics studies word meaning, sense relations (synonymy, antonymy, hyponymy), polysemy versus homonymy, semantic features and componential analysis, prototypes and radial categories, lexical fields and semantic networks, collocation and selectional restrictions, lexical entailment and presupposition, lexical ambiguity resolution in context, semantic change and word formation, and interactions between lexicon and pragmatics
