Here's a breakdown:
* Sarcasm: This is a form of verbal irony where the speaker says the opposite of what they mean, usually with the intent to be humorous or critical. The tone of voice is key to recognizing sarcasm, often being exaggerated or mocking.
* Irony: This is a broader term that refers to a situation where there is a contrast between what is expected and what actually happens. It can be used to highlight hypocrisy, absurdity, or tragic situations.
* Double Entendre: This involves a word or phrase that has two meanings, one of which is often suggestive or humorous. The speaker may use this to create a playful or ambiguous situation.
Examples:
* Sarcasm: "Oh, wonderful! It's raining cats and dogs, just what I needed for my picnic."
* Irony: "The fire station burned down last night. You'd think they'd be better prepared."
* Double Entendre: "I'm going to the bank to deposit my money. I need to get my ducks in a row."
It's important to remember that context is key when interpreting a speaker's meaning. Understanding the speaker's tone of voice, the situation, and their relationship to the listener can all help you determine if they are being literal or not.
