Did you know?
“Lentil-shaped”—that’s the meaning of Latin lenticularis, the parent of English’s 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 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.
