Define and distinguish the three major types of irony, and locate situational irony in a story's ending.
Irony is a gap between expectation and reality, and it comes in three flavors that are easy to confuse. Verbal irony is saying one thing while meaning another (often sarcasm). Dramatic irony is when the audience knows something a character does not. Situational irony is when an outcome is the opposite of what anyone -- character, narrator, or reader -- expected.
Guy de Maupassant's "The Necklace" is built entirely around situational irony. Mathilde borrows a necklace to look wealthy for one night, loses it, and spends ten years of grinding poverty helping pay off a replacement -- only to learn in the final lines that the original necklace was costume jewelry worth almost nothing. The ending does not just surprise us; it reverses the entire meaning of everything that came before it.
Mastery looks like: They can correctly distinguish verbal, dramatic, and situational irony and identify which type governs a given story's ending, with a reason.
Common stumbles: Using "ironic" loosely for any surprising or unlucky event; mixing up dramatic irony (reader knows, character does not) with situational irony (outcome reverses expectation for everyone).
