Did You Know?
Lentil-shaped-that's the meaning of lenticularis, the Latin word that gave us lenticular. It's an appropriate predecessor because a double-convex lens is one that is curved on both sides, giving it a shape similar to that of a lentil. English speakers borrowed the Latin term, adapting it to lenticular, in the 15th century. Lenticularis, in turn, derives from lenticula, which is the source of the English word lentil and a diminutive of the Latin form lent-, lens, meaning "lentil." You probably won't be too surprised to learn that lent-, lens also gave English the word lens.
