Answer:
Hi there! There are three primary types of irony: dramatic, situational, and verbal. Dramatic irony occurs when the audience knows something that the characters don't. Situational irony is the irony of something happening that is very different to what was expected. Verbal irony is a figure of speech. The speaker intends to be understood as meaning something that contrasts with the literal or usual meaning of what he says.
