Point of View
First person pov: Only one "character" in the story is described as "I." All action is filtered through the thoughts and values of this character, who may be trustworthy—or may not.
Second person pov: Rare, but used in contemporary writing. "You" is the primary form of address here, resulting in work which tends to sound very colloquial.
Third person pov: Can be omniscient (see inside and report on thoughts of all the characters), limited omniscient (see inside only one mind), or not omniscient at all. "He," "she," are the primary forms of address.
There are many continua along which a point of view may be described but the chief are:
degree of knowledge of the action;
degree of understanding of the action;
degree of participation in the action.
