The document provides an overview of systemic functional linguistics, which views language as a strategic meaning-making resource that is influenced by social and cultural context. It discusses 21 potential applications of systemic theory and lists four main claims: that language use is functional, its function is to make meanings, these meanings are influenced by context, and language use is a semiotic process of making meanings through choice. The document also describes how context impacts language use through registers, genres, and ideology. Systemic analysis seeks to demonstrate that linguistic texts make multiple meanings simultaneously through experiential, interpersonal, and textual meanings.
