This chapter discusses the relationship between grammar and discourse analysis. It covers topics like grammatical cohesion, reference, ellipsis, substitution, conjunction, theme and rheme, tense and aspect. Grammatical elements like pronouns, verbs and conjunctions are examined in terms of how they contribute to coherence and structure in written and spoken texts. The chapter aims to demonstrate how discourse analysis can provide insights into how local grammatical choices influence the organization of discourse as a whole.
