There are two ways to relate what a person has said: direct and indirect speech. Direct speech uses the person's exact words, while indirect speech conveys the meaning without using their exact words. When changing direct speech to indirect speech, certain changes are usually made, such as changing verb tenses and pronouns. Questions and commands also require specific changes, such as changing the question structure to a statement and changing the introductory verb for commands. Different reporting verbs are used depending on the structure, such as "say" for statements and "ask" for questions.
