Etymology

firearm = fire<combustion> + arm<weapon>

  • fire: From Old English fȳr, referring to combustion or burning. In this context, it denotes the explosive force used to propel the projectile.
  • arm: From Old French arme, meaning "weapon," ultimately derived from Latin arma (tools of war). Here, it signifies the weapon itself.

Etymology Origin:
The term firearm emerged in the late 15th century, combining fire (highlighting the gunpowder-based mechanism) and arm (a general term for weapons). It reflects the technological shift from melee weapons (e.g., swords) to gunpowder-driven projectile weapons. The word’s structure logically mirrors its function: a weapon (arm) powered by combustion (fire).
