- silhouette (n.)
- 1798, from French silhouette, in reference to Étienne de Silhouette (1709-1767), French minister of finance in 1759. Usually said to be so called because it was an inexpensive way of making a likeness of someone, a derisive reference to Silhouette's petty economies to finance the Seven Years' War, which were unpopular among the nobility. But other theories are that it refers to his brief tenure in office, or the story that he decorated his chateau with such portraits.
Silhouette portraits were so called simply because they came into fashion in the year (1759) in which M. de Silhouette was minister. [A. Brachet, "An Etymological Dictionary of the French Language," transl. G.W. Kitchin, 1882]
Used of any sort of dark outline or shadow in profile from 1843. The verb is recorded from 1876, from the noun.

Western cultivation began 552 C.E., when agents from Byzantium impersonating monks smuggled silkworms and mulberry leaves out of China. Chinese si "silk," Manchurian sirghe, Mongolian sirkek have been compared to this and the people name in Greek might be a rendering via Mongolian of the Chinese word for "silk," but this is uncertain.
Also found in Old Norse as silki but not elsewhere in Germanic. The more common Germanic form is represented by Middle English say, from Old French seie, with Spanish seda, Italian seta, Dutch zijde, German Seide is from Medieval Latin seta "silk," perhaps elliptical for seta serica, or else a particular use of seta "bristle, hair" (see seta (n.)).
According to some sources [Buck, OED], the use of -l- instead of -r- in the Balto-Slavic form of the word (Old Church Slavonic šelku, Lithuanian šilkai) passed into English via the Baltic trade and may reflect a Chinese dialectal form, or a Slavic alteration of the Greek word. But the Slavic linguist Vasmer dismisses that, based on the initial sh- in the Slavic words, and suggests the Slavic words are from Scandinavian rather than the reverse.

This is one of the few instances in which an original long e (ee) has become shortened to i. The same change occurs in breeches, and in the American pronunciation of been, with no change in spelling. [Century Dictionary]
