Use the STEAL method (Speech, Thoughts, Effect on others, Actions, Looks) to build a character analysis from indirect evidence.
Writers rarely just tell you who a character is -- they show you, and you have to do the inference. Direct characterization is the rare moment a narrator states a trait outright ("He was a proud man"). Indirect characterization is everything else: what a character says, what they think, how other characters react to them, what they do, and even how they look. English teachers use the acronym STEAL to remember the five channels: Speech, Thoughts, Effect on others, Actions, Looks.
Poe's "The Cask of Amontillado" is a master class in indirect characterization because the narrator, Montresor, never announces his own cruelty -- he reveals it through calm, polite speech while leading a man to his death, and through actions so controlled they read as chilling rather than frantic. The gap between his composed tone and his monstrous plan is the entire character study.
Mastery looks like: They can pull at least three pieces of STEAL evidence from a text and use them to support one clear characterization claim.
Common stumbles: Restating the plot instead of naming a trait; picking a detail without explaining what it reveals about character.
