SYRINGE, a well-known instrument, serving to imbibe or suck in a quantity of fluid, and to squirt or expel the same with violence. The word is formed from the Greek syne, or the Latin frinx, "a pipe."—A syringe is only a single pump, and the water ascends in it on the same principle as in the common sucking pump.
