Other forms: casks
A barrel-shaped container that holds wine or other, usually alcoholic, beverages is called a cask. If you visit a winery, you will often see many rows of wooden wine-filled casks lining the caves and cellars of the winery. If you have a large party, you can open a cask of wine.
Experts aren't exactly sure what the origin of the word cask is. They know that it is a noun that comes from the Middle French word casque or the Spanish word casco, and both mean "helmet," but how we got from helmet to wine-filled barrel-shaped container is unclear. Students may have heard of the word cask from Edgar Allan Poe's famous short story of revenge and murder set in a wine cellar, "The Cask of Amontillado."
