Semantics is the study of meaning in language. It involves examining how words, sentences, and other linguistic elements convey meaning, and how this meaning is interpreted by speakers and listeners. Semantics also considers the relationship between language and the world, and how language is used to represent and communicate about reality. Researchers in semantics often use formal methods to analyze and describe the structure and organization of meaning in language. The field of semantics encompasses a wide range of topics, including lexical semantics (the meaning of words), compositional semantics (how meaning is created in larger linguistic units), and pragmatics (how context influences meaning).Semantics is a key area of study in linguistics, philosophy of language, cognitive science, and computational linguistics.
