The document discusses the differences between direct and indirect narration. Direct narration reports the exact words spoken without changes, while indirect narration does not report the exact words and changes pronouns, verbs, and other elements according to grammar rules. Some of the key rules for changing direct to indirect speech include changing present tenses to past tenses, changing pronouns according to the subject or object of the reported speech, changing words like today to that day, and changing interrogative sentences by removing question marks and changing verbs and auxiliaries.
