Semantics refers to the study of meaning in language, including how words, phrases, and sentences convey specific ideas and concepts. It explores the relationship between language and the world, and how words can have different meanings depending on context and usage. Semantics also examines the nuances and subtleties of language, such as connotations and denotations, and how they contribute to the overall meaning of a message. In essence, semantics is the bridge between language and understanding, allowing us to communicate effectively and accurately convey our thoughts and ideas.
