Third person omniscient also uses third person, but the narrator is the book’s all-seeing, all-knowing “god” and not a single character. The reader knows everything, often before characters know it, and is in on the thoughts and feelings of many characters instead of limited to one. This writing style is not very popular now, largely because most readers find it distant and impersonal compared to a limited viewpoint’s intimacy.

I don’t know what grade you’re in and what books you’ve read, but an example of TPO is the narrator in John Irving’s A Widow for One year.

TP limited is like the narrator in Lahiri’s The Namesake.

RE:
What is the difference between third person limited and third person omniscent?
Please explain.

ex. does not know killer in the mystery novel.

3rd person omniscent, on the other hand, does know everything about the story and is just a third person narrator.

hope that helps.

3rd person limited is when a story is told through the eyes of a character, but it is not that character that is talking. For example, the story is told like this “Bob felt really scared as he was riding the roller coaster. He couldn’t believe that he had actually agreed to ride it with his friends.” The whole story is told just like this just through Bob. 3rd person omniscent [also known as dramatic] is told the same way except that the story can switch people that the story is told through. Like: “Bob felt really scared as he was riding the roller coaster. He couldn’t believe that he had actually agreed to ride it with his friends. John was holding on to the safety bar so hard that he hurt his fingers. John sat there wishing he wasn’t on the roller coaster.”

theres one more 3rd person – objective. this is like a “fly on the wall” kind of narrative.

Third person limited doesn’t know as much. If I remember correctly, they are limited to what can be seen, not thoughts unless people say them…
