Have you ever heard of idioms? This is a good book to learn what they are. The definition is in the front of the book, but basically an idoism is when you use words to explain or express something but the words are usually used to explain or express something else. For example, kicked the bucket would mean someone died or if someone tied the knot they got married.
Monkey Business by Wallace Edwards is an interesting and funny book that takes idioms and shows them in a more literal light. So if someone rises to the occasion it really happens!
