Idioms

An idiom is a combination of words that has a figurative meaning owing to its common usage. An idiom's figurative meaning is separated from the literal meaning. There are thousands of idioms and they occur frequently in all languages. For example when pigs fly means something will never happen, let the cat out of the bag means disclose a secret that was supposed to be kept, don't judge a book by its cover means should not decide upon something based just on outward appearances, etc.

For my idioms I have chosen to do are Hit the books, Scratch someone's back and Get the cat out of the bag.
