Final answer:
A narrator using third-person pronouns and knowing all characters' thoughts and actions is a 'third-person omniscient' narrator. This narrator offers a comprehensive view of the narrative, as opposed to first-person or third-person limited narrators.
Step-by-step explanation:
The student's question pertains to a narrator who uses third-person pronouns such as he, she, and they and possesses knowledge about all characters' thoughts and actions. This type of narrator is known as third-person omniscient. The key characteristic of an omniscient narrator is their god-like perspective, which grants them full knowledge of the story's events, and the internal thoughts and feelings of every character, offering a broad and comprehensive view of the narrative.
Unlike the third-person limited narration, where the narrator may know the inner workings of one or a few characters, the omniscient narrator has no such restrictions. This can be contrasted with second-person narration, where the narrator directly addresses the reader with 'you', and first-person narration, which uses 'I' and is limited to what the narrator character experiences.
