"wood-worker," c.1300 (attested from early 12c. as a surname), from Anglo-French carpenter, Old North French carpentier (Old French and Modern French charpentier), from Late Latin (artifex) carpentarius "wagon (maker)," from Latin carpentum "wagon, two-wheeled carriage, cart," from Gaulish, from Old Celtic *carpentom (cf. Old Irish carpat, Gaelic carbad "carriage"), probably related to Gaulish karros (see car).
Also from the Late Latin word are Spanish carpentero, Italian carpentiero. Replaced Old English treowwyrhta, literally "tree-wright." German Zimmermann "carpenter" is from Old High German zimbarman, from zimbar "wood for building, timber," cognate with Old Norse timbr (see timber). First record of carpenter bee is from 1844.
