carpentry (n.)

"artificer in timber, one who does the heavier sort of wood-working," 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); carriage-maker" (in Medieval Latin "carpenter," properly an adjective, "pertaining to a cart or carriage," from Latin carpentum "wagon, two-wheeled carriage, cart."

This word is from Gaulish, from Old Celtic *carpentom (compare Old Irish carpat, Gaelic carbad "carriage"), which probably is related to Gaulish karros "chariot" (source of car), from PIE root *kers- "to run."

Also from the Late Latin word are Spanish carpintero, Italian carpentiero. It displaced Old English treowwyrhta, etymologically "tree-wright." German Zimmermann "carpenter" is from Old High German zimbarman, from zimbar "wood for building, timber," cognate with Old Norse timbr (see timber). The first record of carpenter-bee, which bores into half-rotten wood to deposit its eggs, is from 1795. A carpenter's rule (1690s) is one that is foldable, suitable for carrying in the pocket.

word-forming element making nouns meaning "place for, art of, condition of, quantity of," from Middle English -erie, from Latin -arius (see -ary). Also sometimes in modern colloquial use "the collectivity of" or "an example of."
