I decided to brush up on old essays from the past and learn a little more about writing. and i realized i don't know the difference between the different perspectives of writing... i.e. 1st, 3rd, and omniscient. I know for first person that the words I, we, and he/she are some key words. Are there any other key things/words that I should know before I try to revise/edit. thank you to anyone who answers.

First person point of view, as you say, is when a narrator tells his or her story using the personal pronouns I, me, my, we, our, ours, etc. Second person point of view refers to how we might directly address a person, for example in conversation, when referring to someone or something as "you" or "yours." Third person point of view is when a narrator tells his or her story from outside the story, an independent observer, using the pronouns he, she, it, his, hers, its, etc. Within the third person point of view are defined the third person limited narrator, who knows and expresses the inner thoughts and feelings of one character, and the third person omniscient, or all-knowing, narrator, who knows and expresses the inner thoughts and feelings of all characters in the story.

If you are focusing on narration from the first person point of view, you may wish to reread from the masters of this vantage point. Three of these are Willaim Faulkner and James Joyce who employ the technique of stream-of-consciousness with their first person narrators. This stream of consciousness is effective in ways such as conveying the inner turmoil of their narrators. Edgar Allan Poe, who utitlizes the privilege of an irrational first person narrator in gothic tales. The singleness of focus that the irrational first person narrator affords contributes so well to the horror of Poe's tales.

As you said, first point of view uses articles such as me, I, we. First POV narration tends to be narrow minded and with the opinion of the character. The other characters thoughts and ideas are portrayed through dialogue whilst the ideas of the main character are expressed through narration and the reader experiences them firsthand
