Functional linguistics is a linguistic theory that emphasizes the functional aspects of language, focusing on how language is used for communication in specific social contexts. Unlike some other linguistic theories that primarily analyze language structure, functional linguistics explores the relationship between the form and meaning of language elements within the context of real-life communication. It investigates how language functions in various situations, how speakers use language to convey meaning, and how different linguistic elements contribute to the overall communicative purpose. In essence, functional linguistics seeks to understand language as a tool for interaction and meaning making in social and cultural contexts.
