What are some clues that someone is being ironic?

Others may have different or additional ideas, but the biggest clue to me is that what the person is saying is opposite what would be expected, AND he has a slight grin on his face.

When trying to determine if someone is being ironic, there are a few clues to look for:

1. Context: Irony often involves a contrast between what is expected and what is actually being said or done. Pay attention to the surrounding circumstances to see if there is a discrepancy or unexpected twist.

2. Tone of voice: Sarcasm, which is a form of verbal irony, is often characterized by a particular tone, with exaggerated emphasis or a certain sarcastic inflection. Listen for any hints of sarcasm or a difference in tone that suggests the person is not being literal.

3. Facial expressions and body language: As you mentioned, a slight grin or smirk can often be a giveaway that someone is being ironic. Pay attention to the person's facial expressions and body language, as they may provide additional clues.

4. Contradictory statements: Irony often involves saying something that is the opposite of what is meant. Look for statements or comments that seem contradictory or go against the expected response in a given situation.

Remember, people might show irony in different ways, and it can sometimes be subjective. It's important to consider the overall context and the person's individual communication style when trying to identify irony.
