Michael Halliday is an internationally renowned linguist who has significantly contributed to theories of language and related areas since the late 1950s. He is best known for developing systemic functional linguistics (SFL), shifting the focus from syntax to a more semiotic approach. SFL analyzes language through three metafunctions - the ideational which conceptualizes the world, the interpersonal which represents the speaker, and the textual which manages discourse flow.
