Stop-gap is a term used to describe a temporary solution to a problem or an interim measure to bridge a gap until a permanent solution is found. Some words that could be used as synonyms include, but are not limited to, band-aid, patch, contingency, makeshift, provisional, and temporary. These words all share the common connotation of being a short-term measure to address a specific issue. However, it is important to note that these words may also carry a negative connotation of being incomplete or inadequate compared to a permanent fix. Ultimately, finding the right term to accurately describe a temporary solution depends on the specific context and tone of the situation.
