Litotes (pronounced lie-toe-teez) is the signature literary device of the double negative. Writers use litotes to express certain sentiments through their opposites, by saying that that opposite is not the case. Don’t worry, it makes more sense with the examples. Examples: “You won’t be sorry” (meaning you’ll be happy); 'you’re not wrong' (meaning you’re right); 'I didn’t not like it' (meaning I did)
