The use of first, second, and third person creates the perspective or point of view of a piece of writing. Writing in first person uses the personal pronouns I, we, me, and us, and the possessive forms my, mine, our, and ours; while second person uses you, and the possessives your and yours..
You use the word I to talk about yourself, which is first person. You use the word you to talk to others, which is second person (and very rare in literature). Those sentences I just wrote are in second person. And what I'm writing now is first person.Third person is describing others.The author isn't involved in the story. just now. Report Abuse. When writing in third person it is as if you are writing as a narrator or a witness to what is going on. But as this narrator or witness, you do not refer to yourself, nor do you say anything unless you count telling the story as saying something.
