Step-by-step explanation:
First person:
First person is like you telling a story. It uses words like I or we. For example "I walked to the library after school," would be an example of first person. You are talking about yourself and what you did.
Second person:
Second person is referring to someone else. It uses words like you. This is like in a choose your own adventure book, with a sentence like "You advanced to the next level," or "You opened the door cautiously." You are talking about someone else, usually the person reading what you are righting.
Third person:
Third person is like you referring to someone in general. Common words for third person are she, he, they, them, or it. It is not always you talking about yourself or someone else. Some common examples are "The girl in the red coat then ate the cookie," or "They were in trouble!"
