What is 3rd person point of view?

THIRD-PERSON NARRATION: Any story told in the grammatical third person, i.e. without using "I" or "we": "he did that, they did something else." In other Words, the voice of the telling appears to be akin to that of the author him- or herself. This is perhaps the most common sort of narration and was particularly popular with the nineteenth-century realist novel. See also third-person omniscient narration; third-person-limited narration; and objective shot.
