c.1373, "haul up and fasten with a rope" (v.), from M.Du. trisen "hoist," from trise "pulley," of unknown origin. Hence at a tryse (1440) "in a very short time," lit. "at a single pluck or pull." The M.Du. word is the source of Du. trijsen "to hoist," and cognate with M.L.G. trissen (source of Dan. trisse, Ger. triezen); its ultimate origin is unknown.
