unexpired

The word "unexpired" describes something that is still valid and has not yet reached its end date. It points to a period of use or legal effect that continues into the present. We often hear it with official documents like passports, visas, driver's licenses, or permits: "My passport is still unexpired, so I can travel." But the term is not limited to those cases.

A coupon is unexpired if you can still redeem it for a discount. A warranty is unexpired as long as the manufacturer still has to cover repairs. Even a job offer or a legal contract can be described this way until it is withdrawn, completed, or reaches a stated deadline.

The key idea is that many things have a limited period during which they are usable, acceptable, or legally effective. When something is unexpired, it is still within that period. Once it becomes expired, that validity or usefulness has ended. So when you check your travel documents, tickets, or coupons, this word simply tells you that the item can still be used.
