1. In grammar, a class of pronoun (and its accompanying verb) that is used to refer to a person or thing other than the speaker or the listener. "He" is a third person pronoun.

2. In writing, a style in which facts or details are presented objectively. This style is used in both creative pieces (often so that the author is not limited to just one character's perspective) and in academic papers (where facts need to be presented without bias or emotion). This essay must be written in the third person because you are stating facts about historical events, not sharing your feelings about them.
