Did you know?

Glaucous came to English—by way of the Latin adjective glaucus—from the Greek glaukos, meaning "gleaming" or "gray." It has been used to describe a range of pale colors from a yellow-green to a bluish-gray. The word is often found in horticultural writing describing the pale color of the leaves of various plants as well as the powdery bloom that can be found on some fruits and leaves. Birders may also recognize the word from the names of several birds, including the glaucous gull and glaucous-winged gull so named for their partially gray plumage. The stem glauc- appears in some other English words, the most familiar of which is glaucoma, referring to a disease of the eye that can result in gradual loss of vision. Glauc- also appears in the not-so-familiar glaucope, a word used to describe someone with fair hair and blue eyes; glaucope is a companion to cyanope, the term for someone with fair hair and brown eyes.
