What does arblast mean?
An arblast is a crossbow — specifically the formidable medieval variety whose steel bow was too strong to draw by hand alone and had to be spanned with a windlass, cranequin, or similar mechanical aid before it could loose its short, heavy bolt, known as a quarrel. The name descends through Old French 'arbaleste', itself a blend of Latin elements meaning bow ('arcus') and the ballista, the great torsion siege engine of antiquity; the word thus preserves, in miniature, the lineage of ancient artillery. Arblasts were feared on European battlefields from roughly the twelfth to the fifteenth centuries because their bolts could punch through mail and even plate armor at ranges beyond those of most hand bows. Today the term survives mainly in historical writing, wargaming, and fantasy fiction, where 'arbalest' is the more familiar spelling of the same weapon. For readers of medieval history, encountering 'arblast' signals authentic period vocabulary rather than a modern invention.

The word 'arblast' fuses two ancient war machines into one name — Latin 'arcus' (bow) and Greek-derived 'ballista' (siege engine) — making it literally a bow-ballista hybrid in both form and etymology.

Etymology of arblast
Arblast comes from Old French 'arbaleste', which entered English in the medieval period as both 'arbalest' and the shortened 'arblast'. The French word combines Latin 'arcus' (bow) with 'ballista', the name of the ancient Roman torsion siege engine ultimately derived from Greek 'ballein' (to throw). The compound thus literally means 'bow-ballista', reflecting how the handheld crossbow miniaturized the mechanics of classical artillery. Cognates appear across Romance languages, such as Italian 'balestra' and Spanish 'ballesta'.
How arblast is actually used
Arblast is a rare, chiefly historical term encountered in texts on medieval warfare, heraldry, and historical fiction; the fuller form 'arbalest' is more commonly met today. It carries no figurative or everyday modern usage.
