shine (n.) Look up shine at
1520s, "brightness," from shine (v.). Meaning "polish given to a pair of boots" is from 1871. Derogatory meaning "black person" is from 1908 (perhaps from glossiness of skin or, on another guess, from frequent employment as shoeshines). Phrase to take a shine to "fancy" is American English slang from 1839, perhaps from shine up to "attempt to please as a suitor." Shiner is from late 14c. as "something that shines;" sense of "black eye" first recorded 1903, American English, in East Side immigrant dialect.
