Did You Know?
One place you might encounter gimbals is on a ship, where they are used to keep compasses and other things level with the horizon in contrast to the pitch and roll of the vessel at sea. The word "gimbal" is an alteration of "gemel," a word for a type of finger-ring popular in the 16th century that could be divided into two separate rings. The word comes from Anglo-French "gemel" ("twin"), which in turn comes from Latin "gemellus," a diminutive of "geminus," the Latin word for "twin."
