What is an idiom? It can be an insult — "He has more brawn than brains." — or a compliment — "She's a real trooper." Idioms add life to our language: "I have ants in my pants." Idioms can cast light on a topic, and they have the power to add color to your language and add punch to your vocabulary. Have FUN WITH IDIOMS, and improve your command of English at the same time!
