The word 'postage' is used to refer to the money or fee that you pay to mail a letter or package. For example, if you want to send a birthday card to your friend who lives far away, you will need to add the postage to the envelope before sending it so that the post office can deliver it to your friend's home. You can buy postage stamps at the post office or from a store and then stick them on the envelope. Postage is important to ensure that your mail reaches its destination, so always double check that you have added the right amount of postage before sending anything through the mail.
