The document discusses functional linguistics theories including Systemic Functional Grammar (SFG) and Speech Act Theory. It covers:
- SFG views meaning as primary, with language having features to perform functions. Two main schools are the Prague School (Jakobson) and Copenhagen School (Halliday).
- Jakobson identified 6 language functions. Halliday identified 3 metafunctions - ideational (experience), interpersonal (interaction), and textual (structure).
- Speech Act Theory sees utterances as doing more than just meaning, with locutionary, illocutionary, and perlocutionary acts. Illocutionary acts include assertives, directives, commissives, expressives,
