bullet: [16] Etymologically, a bullet is a ‘little ball’. It comes from French boulette, a diminutive form of boule ‘ball’, from which English also gets bowl, as in the game of bowls. It originally meant ‘cannon-ball’ as well as ‘rifle or pistol projectile’, but this sense had effectively died out by the mid-18th century. => bowl
bullet (n.)
1550s, from Middle French boulette "cannonball, small ball," diminutive of boule "a ball" (13c.), from Latin bulla "round thing, knob" (see bull (n.2)). Earliest version of bite the bullet recorded 1891, probably with a sense of giving someone a soft lead bullet to clench in the teeth during a painful operation.
