Systemic Functional Grammar (SFG) sees language as a meaning making resource that is shaped by its social context. SFG analyzes language based on three metafunctions - ideational (experiential and logical), interpersonal, and textual. It analyzes clauses based on their mood structure and theme. Mood structure looks at the proposition or proposal of a clause based on the relationship between subject and finite. Theme analyzes how messages are structured from known to unknown information based on theme-rheme patterns. SFG also analyzes the representation of experiences through the system of transitivity involving processes, participants, and circumstances.
