Believe it or not, a rain check is not a weather report. A rain check is a small piece of paper. When can you get a rain check? Well, if you are going to a ball game or some other open-air activity and it is called off because of rain or some other reason, you may receive a rain check. With it you may go there again without paying.

You may also receive a rain check at a shop. As you know, sometimes when you go to a shop to buy something which is on sale, it is sold out. You may ask the assistant to give you a rain check and with it you can go again next time to buy what you need at the sale price.

Here’s another way to use this word. If someone invites you to go somewhere, you would like to go very much but cannot, you may say “May I have a rain check?” This means, “I will come next time.” But you can never say “May I take a rain check?” when your teacher gives you some homework.
