1897, from French décor (18c.), back-formation from décorer "to decorate" (14c.), from Latin decorare "to decorate, adorn, embellish, beautify," from decus (genitive decoris) "an ornament," from PIE root *dek- "to take, accept." It thus duplicates Latin decor "beauty, elegance, charm, grace, ornament." Originally a theater term in English; general use is since 1926.
