The french word for carpenter (also shipwright) is charpentier (m); there is a clear similarity between the words in the two languages. But the French have also the word charpente (f) that means framework, or structure, probably since most structures at the time the words were forming were made of wood. Charpenté means well-built, which probably speaks well of the artisans of the period.
A local chateau was open for visits a few weeks ago; here's some of the charpente that was holding up the roof of a tower. They didn't mess about in those days.
