- n. a soda siphon
- n. a tubelike organ found in animals or elongated cell found in plants.
- v. to transfer (liquid) by means of a siphon.
from the GNU version of the Collaborative International Dictionary of English
- n. A device, consisting of a pipe or tube bent so as to form two branches or legs of unequal length, by which a liquid can be transferred to a lower level, as from one vessel to another, over an intermediate elevation, by the action of the pressure of the atmosphere in forcing the liquid up the shorter branch of the pipe immersed in it, while the continued excess of weight of the liquid in the longer branch (when once filled) causes a continuous flow. The flow takes place only when the discharging extremity of the pipe ia lower than the higher liquid surface, and when no part of the pipe is higher above the surface than the same liquid will rise by atmospheric pressure; that is, about 33 feet for water, and 30 inches for mercury, near the sea level.
- n. One of the tubes or folds of the mantle border of a bivalve or gastropod mollusk by which water is conducted into the gill cavity. See Illust. under Mya, and Lamellibranchiata.
- n. The anterior prolongation of the margin of any gastropod shell for the protection of the soft siphon.
- n. The tubular organ through which water is ejected from the gill cavity of a cephaloid. It serves as a locomotive organ, by guiding and confining the jet of water. Called also siphuncle. See Illust. under Loligo, and Dibranchiata.
- n. The siphuncle of a cephalopod shell.
- n. The sucking proboscis of certain parasitic insects and crustaceans.
- n. A sproutlike prolongation in front of the mouth of many gephyreans.
- n. A tubular organ connected both with the esophagus and the intestine of certain sea urchins and annelids.
- n. A siphon bottle.
- transitive v. To convey, or draw off, by means of a siphon, as a liquid from one vessel to another at a lower level.
from The Century Dictionary and Cyclopedia
- n. A bent pipe or tube with legs of unequal length, used for drawing liquid out of a vessel by causing it to rise in the tube over the rim or top.
- n. In zoology, a canal or conduit, without reference to size, shape, or function; generally, a tube or tubular organ through which water or other fluid passes; a siphuncle.
- n. [capitalized] [NL.] In conchology, a genus of gastropods. Also Sipho (Klein, 1753; Fabricius, 1822) and Sypho (Brown, 1827).
- n. In botany, one of the small peculiar cells surrounding the large elongated central cell in the frond of certain florideous algae. See monosiphonous, polysiphonous, Polysiphonia, pericentral.
- n. A siphon-bottle.
- To convey, as water, by means of a siphon; transmit or remove by a siphon.
- To pass or be conducted through a siphon.
- n. A tubular anal organ of the aquatic bugs of the family Nepidæ, probably respiratory in function.
