Reported speech, or indirect speech, tells what someone said or thought. It requires adjusting tense, time/place expressions, and pronouns. For example:

John: Are you going to the beach today?
 
Me: John asked me if (whether) I was going to the beach that day.
                  ^question      ^tense                 ^time

When you’re telling someone what someone else said earlier, it’s essential to adjust the verb tenses, expressions, word order, and pronouns to represent the changed context and timeline compared to the original conversation.
