The word 'unpaid' is used when you talk about something that hasn't been paid for or when someone hasn't received payment for something they did. For example, when you work for a company and they haven't paid you, you can say that you have unpaid wages. Or, if you have a bill that you haven't paid, you can say that you have an unpaid bill. So, the word 'unpaid' is used to describe something that is owed or due but has not been paid yet.
