This document discusses the differences between direct and indirect (or reported) speech. Direct speech uses quotation marks to report someone's exact words, while indirect speech conveys the general meaning without necessarily using the exact words. When changing direct speech to indirect speech, some grammatical changes are usually required, such as changing pronouns, adverbs of time and place, and verb tenses. The document provides detailed guidelines on how to change different types of constructions like statements, questions, commands, and exclamations into the corresponding indirect speech constructions.
