Getting On My Grammatical Nerves
Okay, okay, let us use this as a teaching moment.
Hyperbole: deliberate extreme exaggeration or overstatement.
Sarcasm: a sharp form of humor, intended to hurt, sometimes conveyed in speech with vocal over-emphasis insincerely saying something which is the opposite of one’s intended meaning.
When the Leader of the Republican Party said that Barack Obama is the founder of Isis, he was not being sarcastic because (1) it was not humorous, and (2) he did not mean the exact opposite.
He was also not using sarcasm because he said he wasn’t.
There is also Satire, which is Hyperbole and Sarcasm with an advanced degree. Donald Trump would not recognize it if it bit him on the butt.
There, I feel better.
