chink: English has three words chink. The one denoting the sharp metallic sound [16] is purely onomatopoeic. The one meaning ‘small hole’ [16] is something of a mystery, but it may be an alteration of chine ‘fissure’ [14] (best known today as the term for a coastal ravine in Hampshire and the Isle of Wight), which came from Old English cinu. Chink as a demeaning term for a Chinese person [19] is a facetious formation based on China or Chinese. [chink etymology, chink origin, 英语词源]
