The character for 'jin', of course, derives from Chinese, as does its pronunciation. The modern Mandarin word is 'r¨¦n' (pronounced like 'zhuhn' in the second tone). The word for 'Japanese' is 'r¨¬b¨§nr¨¦n.' This quite productive morpheme in Japanese is also seen in other words like 'gai-jin', which derives from the Chinese word 'w¨¤ir¨¦n' which today means 'outsider (of a family, etc.)' in Mandarin.
