means The craft of shaping and joining metal—through heating, hammering, cutting, and soldering—into tools, jewelry, or other objects.

from A transparent compound: "metal" + "smith" + "-ing." "Smith" is the deep-rooted one, an Old English word (smið) for a worker in metal, with cousins across the Germanic languages—Old Norse smiðr, Old High German smid. Its older sense was broader, meaning simply a skilled craftsman or maker, which is why we still have wordsmith and the surname Smith, once the most common trade in the village. "Metal" itself came later through Old French from Latin metallum, "mine" or "quarry," borrowed in turn from Greek metallon. So a metalsmith is, quite literally, a skilled maker who works the stuff dug from the earth.
