Linguistic semantics is a subfield of linguistics dedicated to the systematic study of meaning in language. It investigates how linguistic expressions, from individual words and morphemes to phrases, sentences, and larger units of discourse, relate to concepts, ideas, and states of affairs in the world. This research area analyzes the principles governing lexical meaning, compositional meaning (how meanings combine), and the role of context in interpretation, providing foundational insights into the cognitive and communicative functions of human language.
