Etymology
From Portuguese China, perhaps from Hindi चीन (cīn) and ultimately from Sanskrit चीन (cīna, “the Chinese; China”) of uncertain etymology. It is usually thought to be derived from 秦 (Qín, “Qin, Middle Chinese: /d͡ziɪn/, Old Chinese: /*zin/”), the westernmost ancient Chinese state, but other theories have been proposed, including derivation from 晉／晋 (jìn, “Jin, Middle Chinese: /t͡siɪnH/, Old Chinese: /*ʔsins/”), 荊／荆 (jīng, “Jing”), or the Zina of 夜郎 (Yèláng, “Yelang”). <...>
