This document discusses discourse and identity from linguistic and social perspectives. It defines discourse as the organization of language beyond the sentence level, including utterances, texts, and abstract ways of talking about topics. Spoken and written discourse are co-constructed differently. Identity is examined as how individuals understand their relationship to the world and see possibilities for the future, with recognition that identity is non-fixed and constructed through social interaction and membership. Recent social theory and constructionism view social categories and identities as choices in self-representation using language and other means, rather than rigid definitions.
