Satire, sarcasm, and irony are all forms of communication that involve the use of language to convey meaning beyond the literal interpretation. However, they differ in their specific purposes and techniques:

Satire: Satire is a genre of literature, art, or performance that uses humor, irony, exaggeration, or ridicule to criticize or mock individuals, institutions, or societal issues. It often aims to provoke change or bring attention to social or political problems through satire's critical lens. Satire can be found in various forms, such as satirical novels, cartoons, or satirical news shows.

Sarcasm: Sarcasm is a form of communication in which someone says the opposite of what they actually mean, often with the intention to mock, ridicule, or express contempt. It involves using tone, inflection, or context to convey the opposite of the literal meaning. Sarcasm is often characterized by its sharp, biting, or caustic nature and is commonly used in everyday conversations.

Irony: Irony is a rhetorical device or figure of speech that involves expressing something different or opposite to what is expected or intended. It often creates a contrast between what is said and what is meant, leading to a humorous or thought-provoking effect. Irony can be situational (when the outcome is different from what was expected), verbal (when words express the opposite of their literal meaning), or dramatic (when the audience knows something the characters do not).

Satire:

A satirical cartoon that depicts politicians as greedy pigs, criticizing their corruption and self-interest.

A satirical novel that uses humor and exaggeration to expose the flaws and absurdities of a particular social class or institution.

Sarcasm:

"Oh, great. Another meeting. I can't wait to waste more of my time."

"Wow, you're really good at following instructions, aren't you?" (said to someone who made a mistake)

Irony:

A fire station burns down during a fire.

A person who claims to be an environmentalist is seen throwing litter on the ground.

In each example, you can see how satire, sarcasm, or irony is used to convey a deeper meaning or create a contrasting effect. Satire criticizes or mocks, sarcasm expresses contempt or ridicule, and irony creates a contrast between expectations and reality.
