quick-and-dirty

The phrase "quick-and-dirty" is a modern American English compound adjective originating in the mid-20th century, likely from engineering or military slang. Its logic is transparently metaphorical: "quick" denotes speed of execution, while "dirty" implies a lack of polish, thoroughness, or ethical rigor, suggesting something hastily and messily constructed. The conjunction "and" simply links these two qualities. The term captures a pragmatic, often temporary approach, where expediency is prioritized over quality or finesse, and has been widely adopted in fields like software development, prototyping, and informal reporting.

Structure: quick (fast) + and (linking) + dirty (unclean) - quick: From Old English cwic (alive, living, brisk). In this compound, it functions as an adjective meaning "fast, rapid". - and: From Old English and, ond (and, also). In this compound, it functions as a coordinating conjunction linking the two adjectives. - dirty: From Middle English dritty (soiled, unclean). In this compound, it functions as an adjective meaning "unclean, shoddy, or morally questionable".
