équarrir

A technical verb with two distinct uses: to square off a piece of stone or timber (équarrir une pièce de bois), and, in the meat and agricultural industry, to cut up or dispose of animal carcasses — the noun équarrissage refers to the whole rendering industry.

• Le charpentier équarrit la poutre avant de la poser. — The carpenter squares off the beam before installing it.
• L'équarrisseur récupère les carcasses des animaux morts. — The renderer collects the carcasses of dead animals.
• Cette pierre a été équarrie à la main. — This stone was squared off by hand.

Learners encountering équarrissage in the news (about animal-carcass disposal) sometimes assume it's unrelated to the woodworking verb équarrir — both share the same root meaning "to make square/cut precisely," just applied to very different materials.
