cuirer

Cuirer is a narrow, specialized verb meaning to cover or line something in leather — a trunk, a piece of furniture, a book cover (cuirer une malle). It's rare outside leatherworking, upholstery, and bookbinding contexts, and easy to confuse with the far more common cuire (to cook).

• L'artisan a cuiré cette vieille malle en bois. — The craftsman covered this old wooden trunk in leather.
• On cuire encore certains coffrets à la main dans cet atelier. — Some cases are still leather-covered by hand in this workshop.
• Le relieur cuire la couverture avant de la décorer. — The bookbinder leather-covers the cover before decorating it.

Cuirer and cuire are unrelated in meaning despite the near-identical spelling — cuirer is strictly about applying leather to an object, never about cooking, and mixing the two up in writing changes the sentence completely.
