cenacle (n.)

"dining room," usually with reference to the room in which the Last Supper was held, c. 1400, from Old French cenacle, learned variant of cenaille (14c., Modern French cénacle), from Latin cenaculum "dining room," from cena "mid-day meal, afternoon meal," literally "portion of food," from PIE *kert-sna-, from root *sker- (1) "to cut." Latin cenaculum was used in the Vulgate for the "upper room" where the Last Supper was eaten. Related: Cenatical; cenation.
