General Science

  • noun an electrical protection device consisting of a small piece of metal, which will melt when too much power passes through it
  • verb to join together to form a whole
  • verb to draw too much current, causing a fuse to melt


  • (written as FUSE)
    US satellite, the Far Ultraviolet Spectroscopic Explorer, launched in 1999 for observations in the 1000 Ångstrom region of the spectrum with an 0.64m telescope. Its mission was terminated after tehnical problems in 2007.

    (written as FUSE)


  • noun a safety device that protects an electric circuit from an excessive current

Cars & Driving

  • noun a device containing a thin piece of wire which melts when the current is excessive and thus opens the electrical circuit in which it is placed, to protect equipment in the circuit
  • verb to melt, and (sometimes) become united in the process
  • verb to fail as the result of a fuse blowing


  • A protective device, made of a metal strip, wire or ribbon that guards against overcurrent in an electrical system. The device melts if too much current is generated and breaks the circuit.


  • A safety device which contains a section of conductor, such as a wire, which melts when the current passing through it exceeds a specified amount, called the fuse rating. When the conductor melts, the circuit is opened, thus preventing damage to the circuit, device, equipment, or installation it is meant to protect. Also called electric fuse, or cutout (2).

  • noun part of a plug or other electrical circuit that breaks and cuts off the flow of electricity if there is a fault with the current


  • verb to join together to form a single structure, or to join two or more things together


  • noun a length of fast-burning cord which is lit from a safe distance in order to activate an explosive device
  • noun a component designed to detonate a bomb, shell or other explosive device on impact or after a specific period
  • noun a component designed to prevent serious damage or fire, by safely burning out when an excessive electrical charge passes through it

Real Estate

  • noun an electrical safety device containing a piece of a metal that melts if the current running through it exceeds a particular level, thereby breaking the circuit

Origin & History of “fuse”

English has two distinct words fuse. The noun, ‘igniting device’ (17th c.), comes via Italian fuso from Latin fūsus ‘spindle’, a word of unknown origin. Its modern application comes from the fact that the long thin shape of the original gunpowder-filled tubes used for setting off bombs reminded people of spindles. The vulgar Latin diminutive form of fūsus, *fūsellus, gave French fuseau ‘spindle’, which is the ultimate source of English fuselage (20th c.) (etymologically, ‘something shaped like a spindle’). The verb fuse ‘melt’ (17th c.) probably comes from fūsus, the past participle of Latin fundere ‘pour, melt’ (source of English found, foundry, and fusion (16th c.)).
