little moon, crescent

Literally: little moon

The story of the word

μηνίσκος is a little moon, the diminutive of μήνη, and Greek applied it to anything crescent-shaped, including the metal crescents fixed above statues to keep birds off. Opticians took it in the 17th century for a lens convex on one face and concave on the other. Anatomy claimed it in the 19th for the two cartilage crescents in the knee, which is where most people meet the word, usually in bad news from a physiotherapist.
