Characterization or characterisation is the representation of characters (persons, creatures, or other beings) in narrative and dramatic works. The term character development is sometimes used as a synonym. This representation may include direct methods like the attribution of qualities in description or commentary, and indirect (or "dramatic") methods inviting readers to infer qualities from characters' actions, dialogue, or appearance. Such a personage is called a character. Character is a literary element.
The term characterization was introduced in the 19th century. Aristotle promoted the primacy of plot over characters, that is, a plot-driven narrative, arguing in his Poetics that tragedy "is a representation, not of men, but of action and life." This view was reversed in the 19th century, when the primacy of the character, that is, a character-driven narrative, was affirmed first with the realist novel, and increasingly later with the influential development of psychology.
There are two ways an author can convey information about a character:
Direct or explicit characterization The author literally tells the audience what a character is like. This may be done via the narrator, another character or by the character themselves.
Indirect or implicit characterization The audience must infer for themselves what the character is like through the character's thoughts, actions, speech (choice of words, manner of speaking), physical appearance, mannerisms and interaction with other characters, including other characters' reactions to that particular person.
Characters in theater, television, and film differ from those in novels in that an actor may interpret the writer's description and dialogue in their own unique way to add new layers and depth to a character. This can be seen when critics compare, for example, the 'Lady Macbeths' or 'Heathcliffs' of different actors. Another major difference in drama is that it is not possible to 'go inside the character's head' in the way possible in a novel, meaning this method of character exposition is unavailable.
