A character (sometimes known as a fictional character) is a person or other being in a narrative (such as a novel, play, television series, film, or video game). The character may be entirely fictional or based on a real-life person, in which case the distinction of a "fictional" versus "real" character may be made. Derived from the ancient Greek word χαρακτήρ, the English word dates from the Restoration, although it became widely used after its appearance in Tom Jones in 1749. From this, the sense of "a part played by an actor" developed. Character, particularly when enacted by an actor in the theatre or cinema, involves "the illusion of being a human person". In literature, characters guide readers through their stories, helping them to understand plots and ponder themes. Since the end of the 18th century, the phrase "in character" has been used to describe an effective impersonation by an actor. Since the 19th century, the art of creating characters, as practiced by actors or writers, has been called characterisation.
The study of a character requires an analysis of its relations with all of the other characters in the work. The individual status of a character is defined through the network of oppositions (proairetic, pragmatic, linguistic, proxemic) that it forms with the other characters. The relation between characters and the action of the story shifts historically, often miming shifts in society and its ideas about human individuality, self-determination, and the social order.

In fiction writing, authors create dynamic characters by many methods. Sometimes characters are conjured up from imagination; in other instances, they are created by amplifying the character trait of a real person into a new fictional creation, or are created from scratch as a matter of expediency.
