China (n.)youdaoicibaDictYouDict
Asian country name, 1550s, of uncertain origin, probably ultimately from Sanskrit Cina-s "the Chinese" (earliest European usage is in Italian, by Marco Polo), perhaps from Qin dynasty, which ruled 3c. B.C.E. Latinized as Sina, hence sinologist. The Chinese word for the country is Chung-kuo (Wade-Giles), Zhongguo (Pinyin).
