What is all the pionts of view and how do i tell the difference

First Person Point of View

A story told from the first person point of view involves the narrator as part of the story, and usually features the following pronouns: I, me, mine, our, we, us, etc.

Second Person

Very rare in literature, this point of view treats the reader as the main character in the story. Other characters refer to the reader as "you." Descriptions are based on what you would see if you were in that situation. This narrative voice is generally reserved for explanatory articles and how-to books, but adventurous writers will occasionally pen a short story or novel in the second person. 

Third Person Point of View

Third person point of view is told by a narrator who is not part of the story and generally uses pronouns such as: he, she, it, they, them, him, her, its, etc. There are three type of third person narration: omniscient and limited.

1st person: main character pov

2nd person: (Rare) readers pov

3rd: narrator pov

POV=Point of View.
