The word 'backlog' is used to refer to a large amount of work or tasks that have not been completed yet. It can be used in different contexts, for example, a backlog of emails that need to be answered, a backlog of orders that need to be shipped, or a backlog of homework assignments that need to be completed. Essentially, a backlog is a list of things that need to be done but for some reason, haven't been done yet.
