The phrase "temporary purpose" typically refers to a goal or objective that is intended to be achieved for a limited time, rather than being permanent. It could refer to something as simple as borrowing an item from someone with the understanding that it will be returned when no longer needed, to more complex situations such as setting up a temporary shelter for victims of a natural disaster until they can return to their homes or finding temporary housing while renovations are being done on one's permanent residence. The key characteristic is that the purpose is not intended to continue indefinitely but rather has an end point in sight.
