The Surprising Origins of the Word “Tumbler” for Drinking Glasses | October 05 2025, 15:32

In our language, glasses are called tumblers. I decided to find out why, because a tumbler is essentially an acrobat.

There are two mutually exclusive theories. According to one, the original tumbler glasses had a rounded or slightly convex bottom, which allowed them to “rock” or “tumble” (to tumble), but not tip over completely. So, a tumbler in this sense is kind of like a “weeble.” According to the other, they were specifically made so they could not be put down on the table open, because, say on a ship, they could tip over and the valuable rum would spill out.
