What is stopgap?

Stopgap is a temporary measure or solution used to fill a gap or address an immediate problem, until a more permanent solution can be implemented. It can refer to various contexts such as a temporary fix in technology, a short-term measure in business, a makeshift solution in construction or maintenance, or a makeshift barrier for preventing something from getting through. Stopgap measures are often implemented to prevent further damage or to mitigate the negative effects of a problem while a long-term or permanent solution is being developed.
