- stop (v.)
- O.E. -stoppian (in forstoppian "to stop up, stifle"), along with M.L.G. stoppen, O.H.G. stopfon (Ger. stopfen) a W.Gmc. borrowing from V.L. *stuppare "to stop or stuff with tow or oakum" (cf. It. stoppare, Fr. étouper "to stop with tow"), from L. stuppa "coarse part of flax, tow." Plugs made of tow were used from ancient times in Rhine valley. Sense of "bring or come to a halt" (mid-15c.) is from notion of preventing a flow by blocking a hole, and the word's development in this sense is unique to English, though it since has been widely adopted in other languages; perhaps influenced by L. stupere "be stunned, be stupefied." The noun is first recorded late 15c. Stop-and-go (adj.) is from 1926.
