Leak


Definition:

  • (v.) A crack, crevice, fissure, or hole which admits water or other fluid, or lets it escape; as, a leak in a roof; a leak in a boat; a leak in a gas pipe.
  • (v.) The entrance or escape of a fluid through a crack, fissure, or other aperture; as, the leak gained on the ship's pumps.

  • (n.) To let water or other fluid in or out through a hole, crevice, etc.; as, the cask leaks; the roof leaks; the boat leaks.
  • (n.) To enter or escape, as a fluid, through a hole, crevice, etc. ; to pass gradually into, or out of, something; -- usually with in or out.
