Did You Know?

"Lentil-shaped"-that's the meaning of "lenticularis," the Latin word that gave us today's word. 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."
