A cannon (artillery piece)


Borrowed around 1400 from Old French canon, from Italian cannone, from Latin canna.

This spelling was not fixed until about 1800.[1][2]



cannon (plural cannon or cannons)

  1. A complete assembly, consisting of an artillery tube and a breech mechanism, firing mechanism or base cap, which is a component of a gun, howitzer or mortar. It may include muzzle appendages.[3]
  2. A bone of a horse's leg, between the fetlock joint and the knee or hock.
  3. (historical) A large muzzle-loading artillery piece.
  4. (sports, billiards, snooker, pool) A carom.
    In English billiards, a cannon is when one's cue ball strikes the other player's cue ball and the red ball on the same shot; and it is worth two points.
  5. (baseball, figuratively, informal) The arm of a player that can throw well.
    He's got a cannon out in right.
  6. (engineering) A hollow cylindrical piece carried by a revolving shaft, on which it may, however, revolve independently.
  7. (printing) Alternative form of canon (a large size of type)

Usage notes[edit]

The unchanged plural is preferred in Great Britain and Ireland, while North Americans and Australians tend to use the regular plural cannons.

On aircraft, autocannons are sometimes called "cannons" for short.
