sunshine n.

Old English sunne "the sun," from Proto-Germanic *sunno (source also of Old Norse, Old Saxon, Old High German sunna, Middle Dutch sonne, Dutch zon, German Sonne, Gothic sunno "the sun"), from PIE *s(u)wen-, alternative form of root *sawel- "the sun."

Old English sunne was feminine (as generally in Germanic), and the fem. pronoun was used in English until 16c.; since then masc. has prevailed. The empire on which the sun never sets (1630) originally was the Spanish, later the British. To have one's place in the sun (1680s) is from Pascal's "Pensées"; the German imperial foreign policy sense (1897) is from a speech by von Bülow.

1520s, "brightness, radiance," from shine (v.). Indicating "sunshine," and paired with rain (n.), from 1620s. Meaning "polish given to a pair of boots" is from 1871.

For the American English slang meaning "a prank, a trick," see monkey-shines. Often also "a fancy, a liking," as in phrases such as take a shine to, "fancy," attested by 1830 in representations of Yankee dialect; shine up to "attempt to please as a suitor by making a brilliant impression" (1882).

The derogatory meaning "black person" is attested by 1908, perhaps from glossiness of skin or, on another guess, from frequent employment as shoeshines.
