The word 'defective' means that something is not working properly or has something wrong with it. It is often used to describe items or products that do not function as they should. For example, if a toy is missing a piece or doesn't move like it's supposed to, it may be considered defective. People might also use the term 'defective' to describe something that is flawed or has a defect, like a car that has a faulty engine. It's important to understand when something is considered defective so that you can either fix it or get a replacement.
