Functional: Michael Halliday proposed that language is primarily a social tool for making meaning, not just a system of grammatical rules. It focuses on how English is shaped by its context and the needs of its users, with every utterance simultaneously serving three main purposes. These functions, known as meta functions, include the ideational, which represents our experience of the world; the interpersonal, which enacts social relationships; and the textual, which organises the message into a coherent text.
