Ad hockery refers to an improvised, unplanned, and often temporary solution to a problem. Synonyms for ad hockery include makeshift, stopgap, impromptu, expedient, quick fix, Band-Aid, jury-rigged, spur-of-the-moment, and ad-lib. A makeshift entails something put together out of available resources, while a stopgap solution is meant to temporarily fill a gap. An impromptu solution is unplanned or spontaneous and may be practical, while expedients are actions taken based on practicality rather than principle. Quick fixes may later require further remedial efforts, and a Band-Aid is a temporary solution for something until it can be fixed permanently. Jury-rigged or jerry-built are makeshift solutions, while ad-lib refers to unprepared, improvised actions or words.
