The document discusses three types of irony - dramatic, situational, and verbal. It provides examples of each: dramatic irony is when the audience knows something the characters don't, like Romeo believing Juliet is dead from the sleeping potion; situational irony is when the ending is unexpected, like Juliet waking to find Romeo dead; verbal irony is saying one thing but meaning another, like Mercutio joking he will be a "grave man" but actually foreshadowing his death.
