POV stands for Point of View.
It's writing/viewing the scene from inside the head of a particular character. Usually, the deeper you can get into a POV, the more connected a reader feels to that character. Obviously, the writer doesn't always want you to know what's in every character's mind, so part of the creation process is deciding how many, and whose, POVs to write from for the story.
It's not always easy to determine, either. I know lots of authors who have gotten halfway through a manuscript before it dawns on them that the POV should be from a different character.
Here are the basics:
First person POV - is when the main character refers to themselves as 'I'. The story is viewed/experienced from that one character's point of view. Sometimes an author will do a 2nd or 3rd POV in combination with that - either from the first person or the third person. Diana Gabaldon does that in her Outlander series. Claire is always written in the first person, and Jamie - her husband - and all other characters - are written in the third person.
Example of first person from my book, Blinke It Away - When Bess Blinke is up on Mount Kaala
The air smelled sweet and clean. I picked up the scent of something earthy and - apples? Hawaii didn't have regular apple trees, but rose and mountain apples grew there. I climbed and searched for them. Soon, a group of mountain apple trees were within sight, bursting with massive clusters of the small, red fruit. Smashed ones lay on the ground under and surrounding them. I hurried closer, hit something slick, slid downhill, and landed when my back slammed into a tree trunk. The impact made the pain in my head throb all over again.
Third Person POV - is when the 'narrator' (the author) tells you what a character is thinking or doing.
Example of third person from my book, Alias: Mitzi & Mack - From Stanley & Catherine's first meeting. It's in Stanley's POV. Notice that, although I'm telling you both characters' actions and words, you only know Stanley's thoughts, not hers.
If she wanted sympathy from him, she wasn't going to get it. "Just the same, I don't like being treated like that. I still think we should forget the whole thing. Don't worry. I'll never tell a soul I was here."
"Please don't go." She stood, then approached him. "I'd like to find out more about you. I'll pay you a thousand dollars if you'll simply sit once more."
A thousand dollars to sit? "Okay." As he sat, he wondered if she also threw money from the car windows for the fun of watching poor people fight for it.
I have a workshop presentation for POV that goes into much further detail. Contact me if you'd like me to present it for your group.
I believe the only way to get through the slings and arrows life throws at all of us is to find the humor.
