Definitions

from The American Heritage® Dictionary of the English Language, 4th Edition

  • n. A cord of readily combustible material that is lighted at one end to carry a flame along its length to detonate an explosive at the other end.
  • n. A mechanical or electrical mechanism used to detonate an explosive charge or device such as a bomb or grenade: "A mechanical . . . switch is used to initiate the fuzes” ( International Defense Review).
  • transitive v. To equip with a mechanical or electrical fuse: "The bomb . . . was fuzed and timed to explode after the aircraft had taken off” ( Aviation Week & Space Technology).
  • transitive v. To liquefy or reduce to a plastic state by heating; melt.
  • transitive v. To mix (constituent elements) together by or as if by melting; blend.
  • intransitive v. To become liquefied from heat.
  • intransitive v. To become mixed or united by or as if by melting together: "There was no separation between joy and sorrow: they fused into one” ( Henry Miller). See Synonyms at mix.
  • n. A safety device that protects an electric circuit from excessive current, consisting of or containing a metal element that melts when current exceeds a specific amperage, thereby opening the circuit.

  • n. A cord that, when lit, conveys the fire to some explosive device.
  • n. The mechanism that ignites the charge in an explosive device.
  • n. A device to prevent the overloading of an electrical circuit.
  • n. Indicating a tendency to lose one's temper.
  • v. To melt together; to blend; to mix indistinguishably.

  • transitive v. To liquefy by heat; to render fluid; to dissolve; to melt.
  • transitive v. To unite or blend, as if melted together.
  • intransitive v. To be reduced from a solid to a fluid state by heat; to be melted; to melt.
  • intransitive v. To be blended, as if melted together.
  • n. A tube or casing filled with combustible matter, by means of which a charge of powder is ignited, as in blasting; -- called also fuzee. See fuze.
  • n. a mechanism in a bomb, torpedo, rocket, or artillery shell, usually having an easily detonated explosive charge and activated by the shock of impact, which detonates the main explosive charge. Some fuses may have timing mechanisms, delaying the explosion for a short time, or up to several days after impact. Fuses activated by other mechanisms more sophisticated than impact, such as proximity or heat, are used in modern weapons such as antiaircraft or antimissile missiles.
  • n. A wire, bar, or strip of fusible metal inserted for safety in an electric circuit. When the current increases beyond a certain safe strength, the metal melts, interrupting the circuit and thereby preventing possibility of damage. It serves the same function as a circuit breaker.

from The Century Dictionary and Cyclopedia

  • To melt; liquefy by heat; render fluid.
  • To blend or unite as if by melting together.
  • Synonyms Dissolve, Thaw, etc. See melt.
  • To amalgamate.
  • To melt; be reduced from a solid to a fluid state by heat.
  • To become intermingled and blended as if melted together.
  • n. A tube, casing, ribbon, etc., of various materials, filled or saturated with a combustible compound, and used as an exploder for firing a blast or for igniting any exploding charge, as of a military shell.
  • n. The track or trail of a buck in the grass. Also fusee.
  • n. In electricity, a piece of conductor, inserted into an electric circuit, which is of less current-carrying capacity than the rest of the circuit, and therefore under excess of current melts and opens the circuit.
