The word 'prepaid' is used to describe something that has been paid for in advance. For example, a prepaid phone plan is a plan where you pay for your minutes or data in advance instead of after you have used them. Similarly, a prepaid gift card is a gift card that someone has already paid for, so you can use it to buy things without having to pay for them yourself. It is important to understand the concept of prepaid when you want to buy something online or sign up for a service where you have to pay in advance.
