Systemic Functional Grammar (SFG) is a theory of language developed in the 1960s by Michael Halliday that views grammar as a social semiotic system. SFG analyzes authentic language use within a social and cultural context. It interprets language as a network of systems for making meanings and aims to explain the relationship between linguistic forms and the functions they serve. SFG analyzes texts using three metafunctions: the ideational, which relates to content; the interpersonal, which relates to interaction; and the textual, which relates to organization. Context is analyzed across three parameters: field, tenor, and mode.
