Here are three main types of irony:
* Verbal irony: This is when someone says something that is the opposite of what they mean. For example, if you are caught in a downpour and say "Lovely weather we're having," you are using verbal irony.
* Situational irony: This is when something happens that is the opposite of what is expected. For example, if a fire station burns down, that would be a case of situational irony.
* Dramatic irony: This is when the audience knows something that the characters in a story do not. For example, if you are watching a movie and know that the killer is hiding in the closet, but the character in the movie is completely unaware, that is dramatic irony.
Irony is a powerful tool that can be used to add humor, suspense, and complexity to a story or conversation. It can also be used to highlight social or political issues.
