1st POV... one main character tells the story from their POV throughout the story without having any indication of what other characters motives or thoughts may be unless they tell them but can see outside emotions and actions of the other characters but they can't read minds.
2nd POV..(rarely used) this POV allows the writer to address the reader directly using the pronoun YOU, usually reserved for instructional manuals, because it adds intimacy between writer and reader
3rd POV... can work a couple of ways...telling the story through one perspective using the pronouns he, she, or they...Third person limited POV the reader only gets to read the thoughts of one main character. ... BUT can be told in 3rd person multiple POV, several main characters all contributing to the story
3rd.Omniscent..is told from a narrator who knows all, sees all......the writer knows and can reveal at any time anything and everything about any of the characters (this includes past, present, and future,... what's happening anywhere at anytime to anyone,... can interpret any characters motive's, action's, or thoughts....Can reflect, judge and reveal truths)
For beginners 3rd person POV limited is considered the easiest to master
