Which narrative perspective allows the narrator to know everything about one character?

The narrative perspective that allows the narrator to know everything about one character is known as Third Person Limited. In this perspective, the narrator provides a deep and focused insight into the thoughts, feelings, and experiences of a single character, while still narrating the story from a third-person standpoint. This technique enables readers to connect intimately with that character's internal struggles and motivations, but does not provide access to the thoughts and feelings of other characters, keeping the narrative constrained to that one individual's perspective.

Third Person Omniscient, on the other hand, gives the narrator access to the thoughts and feelings of all characters in the story, which is broader than Third Person Limited. Objective Third Person presents only observable actions without access to any character's internal thoughts or feelings, making it less personal than Third Person Limited. First Person offers a deeply personal perspective but is confined to the experiences and observations of one character who recounts the story from their own viewpoint. Therefore, Third Person Limited is distinct in its ability to delve deeply into the knowledge of one particular character while maintaining a narrative distance from others.
