Etymology

Origin of bayonet

1605–15; < French baïonnette, after Bayonne in France (where the weapon was first made or used); see -ette

Explanation

A bayonet is a knife attached to the end of a rifle. This makes the rifle capable of even more violence than before. This handy extension to the business end of a rifle gets its name from the French city of Bayonne. It's thought to have developed when French peasantry ran out of ammo and stuffed their knives into the muzzles of their muskets. A bayonet makes the rifle more versatile: besides shooting people at a distance, it's now more deadly in hand to hand combat. With a bayonet, you've got a gun and knife in one package.
