Idioms are phrases that we use to describe something that is happening or a feeling. The words that we use are expressions that do not really mean what they say. It is important to know what these phrases mean so that you will understand what people are really talking about.
to “let the cat out of the bag” means to tell a secret
“in the doghouse” means you are in real trouble
“keep your fingers crossed” means to wish you good luck.
Take the cards out of the bag and try to match up all the idioms you know with their meanings. Then read the others and see if you can figure out what they mean.
