This work comprises a collection of the writings of Ruqaiya Hasan, an influential figure in the systemic functional linguistic learning school. It discusses the relation between text and context and the realization of context in language; the ''network'', which is outlined as analytic tool which can be applied at two strata of language, the lexico-grammatical and the semantic; as well as aspects of the social structure that are implicated in the way cultures and subcultures express themselves.
