French 'vignette' (little vine) — a manuscript ornament that evolved into a brief literary sketch.
A brief evocative description, account, or episode; a small illustration or decorative design, originally one of vine leaves or tendrils; a photograph or portrait with edges that gradually shade off into the background.
From French 'vignette,' a diminutive of 'vigne' (vine), from Latin 'vīnea' (vineyard, vine), from 'vīnum' (wine), from Proto-Indo-European *wóyh₁nom (wine). The original meaning was a small decorative design of vine leaves and tendrils used as a border ornament in medieval manuscripts and early printed books. The sense extended to any small decorative illustration, then to a small portrait or photograph with fading edges
The word 'vignette' passed through five distinct meanings in sequence: vine tendril (botanical) -> vine-leaf decoration in manuscripts (decorative) -> small illustration in a book (artistic) -> photograph with faded edges (photographic) -> brief evocative sketch (literary). Each meaning grew naturally from the last, creating an unbroken chain from the vineyard to the writing desk.
