silhouette

the word 'silhouette' entered english in the 19th century from french, named after étienne de silhouette, an 18th-century french finance minister. his name became associated with things done cheaply, as his austere economic policies were unpopular, and the inexpensive profile portraits cut from black paper were derisively called 'portraits à la silhouette'. the term thus originates as an eponym, a word derived from a person's name. it transitioned from a label for a frugal art form to its current general meaning denoting a dark outline or shadow.

this word is a loanword adopted as a single unit from french. it does not contain separable, meaningful morphemes within modern english spelling.
