*gwele-

"pertaining to the process of building up" (especially in metabolism), 1876, with -ic + Greek anabolē "that which is thrown up; a mound," from anaballein "to throw or toss up," from ana "up, upward" (see ana-) + ballein "to throw" (from PIE root *gwele- "to throw, reach").

type of crossbow, also arbalist, c. 1300, from Old French arbaleste "large crossbow with a crank" (12c., Modern French arbalète), from Vulgar Latin *arbalista, from Late Latin arcuballista "catapult," from Latin arcus "bow" (see arc (n.)) + ballista "machine for throwing projectiles" (from PIE root *gwele- "to throw, reach"). German Armbrust is from the same French word but mangled by folk etymology. Related: Arbalester.

The missile of the arbalist was discharged with such force as to penetrate ordinary armor, and the weapon was considered so deadly as to be prohibited by a council of the church except in warfare against infidels. [Century Dictionary]
