Javelin

A javelin is a light spear designed primarily to be thrown, historically as a ranged weapon. Today, the javelin is predominantly used for sporting purposes such as the Javelin throw. The javelin is nearly always thrown by hand, unlike the sling, bow, and crossbow, which launch projectiles with the aid of a hand-held mechanism. However, devices do exist to assist the javelin thrower in achieving greater distances, such as spear-throwers or the amentum.

A warrior or soldier armed primarily with one or more javelins is a javelineer.

The word javelin comes from Middle English and it derives from Old French javelin, a diminutive of javelot, which meant spear. The word javelot probably originated from one of the Celtic languages.
