Ébauche

Ébauche (loanword from French, meaning blank, outline or sketch) is a term used in art to denote the first preliminary underpainting or quick sketch in oils for an oil painting. One early criticism of Impressionist painting was that its practitioners sought to elevate the status of the ébauche to the level of finished painting. Horology, clockmaking and watchmaking appropriated the term ébauche to refer to an incomplete or unassembled watch movement and its associated components. The French term is regularly used by English-speaking artists and art historians, as well as horologists and hobbyists.
