Meaning of SIPHON in English

I. noun

( -s )

Etymology: French siphon, from Latin sipho, siphon tube, pipe, siphon, from Greek siphōn; probably akin to Latin tibia shinbone


a. : a tube bent to form two branches of unequal effective length by which a liquid can be transferred to a lower level over an intermediate elevation by the pressure of the atmosphere in forcing the liquid up the shorter branch of the tube immersed in it while the excess of weight of the liquid in the longer branch when once filled causes a continuous flow that takes place only when the discharging extremity is lower than the liquid surface and when no part of the tube is higher above that surface than the same liquid will rise by atmospheric pressure

b. : a channel through which water passes as if in a siphon

c. : inverted siphon

d. usually syphon : a bottle for holding aerated water that is driven out through a bent tube in its neck by the pressure of the gas when a valve in the tube is opened

(2) : a dorsal tube that carries away waste water — see clam illustration

b. : an anterior channel-shaped prolongation of the mantle in many gastropods serving to conduct water to the gills and often being protected by a grooved extension of the margin of the shell — see snail illustration

c. : the swimming funnel of a cephalopod
