This is my favorite perspective to write. You watch everything play out from the view of a main character, usually the main character but sometimes it comes from the villain's POV or the Main Character's best friend. You step into the character's shoes. You feel their emotions and you hear their thoughts.
In this POV, the articles are all first-person (i.e. I, me, mine, my, etc.). For an example of this, you can read any my blog Story Snippet blogs (here) and/or most of my Character Introduction blogs (here).
This POV generally isn't used for fiction writing because it's expository. It's used for debates, legal forms, emails, letters, etc. The articles You, you're, your, etc. are used for this. This is also the POV most bloggers use when talking to you their reader.
Third-person is popular and used by many authors and writers. The story is told from the perspective of an unbiased perspective, usually a narrator. This person can be omniscient and know all there is to know or limited. Here's the difference:
The omniscient narrator can see the mind, heart, and thoughts of each person in the story. Some examples of this are Pride and Prejudice by Jane Austen, Catch-22 by Joseph Heller, and The Scarlet Letter by Nathaniel Hawthorne.
The limited narrator, unlike the omniscient, only knows the emotions, thoughts, and actions of one person. Examples of this: The Anita Blake Novel Series by Laurell K. Hamilton, The Dark Hunter Series by Sherrilyn Kenyon, and the Throne of Glass Novels by Sarah J Maas.
I love reading this POV but I have a hard time writing it as seen in my Valentine's post (here) and I had to have a friend help me out on it (Shout to, AJ Sims. You can find his links to the right on your computer).
This one intrigues me the most. It's a narrative point of view but the narrator has a twisted or biased point of view. Instead of a narrator who is unaffected by the stories plot or has no feeling to any character. This narrator picks one character or group of characters to relate to and consistently lifts them up while bashing the other side. I've thought about writing like this from a Villain's POV after everything has been done and is long passed. Maybe one of my Villain's may get their own story. *hint, hint*
