Final answer:
A third-person omniscient narrator is a character outside the story who has access to all information in the story and can include internal monologue, motives, thoughts, and feelings of all characters.
Step-by-step explanation:
A narrator who has the ability to move freely through the consciousness of any character and has complete knowledge of all the external events of the story is called a third-person omniscient narrator. This type of narrator is able to observe and narrate from an all-knowing perspective and can include internal monologue, motives, thoughts, and feelings of all characters. The third-person omniscient narrator is written by a character outside of the story who has access to all information in the story and does not use the pronouns 'I,' 'you,' or 'we.'
