Semantic theory is a branch of linguistics that studies meaning in language. It explores how words, phrases, and sentences convey meaning and how context influences interpretation. This theory helps us understand the relationship between language and the concepts it represents. One key aspect of semantic theory is the distinction between denotation and connotation. Denotation refers to the literal meaning of a word, while connotation involves the emotional or cultural associations that come with it. By examining these elements, semantic theory provides insights into how language shapes our understanding of the world.
