The word 'warranty' is used when someone is buying a product and wants to make sure they are protected in case something goes wrong with the product. A warranty is a written promise from the company that made the product that they will fix or replace the product if it breaks or doesn't work properly within a certain amount of time. You often see warranties with electronic devices, appliances, and cars. It's important to read the warranty before you buy something to understand what it covers and for how long.
