Formation
Borrowing
Borrowed from
French baïonnette

Pronunciation

  • IPA: /ˈbeɪənɪt/, /ˈbeɪənɛt/, /ˌbeɪəˈnɛt/[1]

Etymology

It is borrowed from French baïonnette,[2][3][4][5] after Bayonne, the town in southwestern France where the weapon was first made.[2][3][4][5][6] Etymonline also allows a diminutive of Old French bayon “crossbow bolt”.[5]

Earliest recorded meaning

A short flat dagger (1611).[7][4][5]

Semantic evolution

The French word could mean a dagger or knife,[2] and that was its first English sense.[7][4] By 1672 it meant a steel blade fixed to the muzzle of a musket or rifle,[7][4][5] at first with its handle inserted into the barrel.[7][1] The American Heritage Dictionary dates the present sense to 1704 and Merriam-Webster to 1689.[2][3] It was later used for military force in the abstract (1774), for soldiers armed with bayonets (1780), and for a pin that locks into a slot, as in a bayonet fitting.[7][6]
