Explanation: an irony is a statement or situation that seems contradictory. In literature there are three main types of irony: verbal irony, situational irony and dramatic irony. Verbal irony is when words express something contrary to truth or someone says the opposite of what they really feel or mean (it is often sarcasm). Situational irony is when what happens is different from what is expected to happen. Dramatical irony is when the audience knows something that the characters don't know. Irony is used to make surprising, interesting, or amusing contradictions in a literary work.
