Reported speech, also known as indirect speech, is a way of reporting what someone has said by changing some of the words while retaining the same meaning. Key changes include changing pronouns like "I" and "you" to the third person and changing tenses. Common reporting verbs used in reported speech include say, ask, offer, promise, agree, refuse, tell, order, warn, remind, advise, and invite. The structure can change depending on whether it is reporting a statement, question, request, order, promise or other type of utterance.
