A voucher is a document or certificate that gives you the right to receive something specific, usually a product, service, or amount of money. Think of it like a paper promise: someone officially says “the person holding this can get X from us.”

Schools sometimes use vouchers in education debates. Instead of sending every child to their assigned neighborhood school, some communities give families education vouchers (a set amount of money) that they can use to help pay for the school of their choice, whether public or private. It's like getting a gift certificate for education rather than being told exactly where to shop.

You might encounter vouchers in everyday life too. A store might give you a voucher for $10 off your next purchase if something went wrong with your order. Hotels might give vouchers to airline passengers when flights get canceled, promising to cover a night's stay. Summer camps sometimes offer vouchers that families can use to reduce the cost of attendance.

The key idea is that a voucher represents value you can claim later. Unlike cash, which you can spend anywhere, a voucher usually works only for specific things or at specific places. When you vouch for someone, you're basically acting like a voucher yourself: you're promising that person is trustworthy or capable.
