This document discusses direct and indirect speech. Direct speech conveys the original words spoken without changes. Indirect speech reports what was said by making some changes, such as changing verb tenses and pronouns based on the context. The key differences are that direct speech uses quotation marks while indirect speech uses the word "that" and changes verbs and pronouns. The document provides examples of changing direct speech to indirect speech based on tense, including changing will to would for future tense. It also notes that tense may not change if the reported speech expresses a universal truth.
