kettle (n.)
Old English cetil (Mercian), from Latin catillus "deep pan or dish for cooking," diminutive of catinus "bowl, dish, pot." A general Germanic borrowing (compare Old Saxon ketel, Old Frisian zetel, Middle Dutch ketel, Old High German kezzil, German Kessel). Spelling with a -k- (c.1300) probably is from influence of Old Norse cognate ketill. The smaller sense of "tea-kettle" is attested by 1769.
