Origin & History of “grate”

Grate ‘framework for holding burning fuel’ (14th c.) and grate ‘rub’ (15th c.) are different words. The former comes via Old French grate ‘grille’ and vulgar Latin *grāta from Latin crātis ‘wickerwork, hurdle’. Grate ‘rub’ is ultimately Germanic (its ultimate ancestor was the Germanic verb *krattōn, source of modern German kratzen ‘scratch’), but it reached English via Old French grater ‘scrape’. Gratin (19th c.) comes from the derived French noun gratin.
