Did You Know?

The chameleon is probably best known for the ability to change colors - but when the ancients named this lizard, they apparently had other qualities in mind. "Chameleon" comes to us, via Latin, from Greek chamaileōn, a combination of "chamai" ("on the ground") and "leōn" ("lion") - a tribute, perhaps, to the lizard's fearsome aspect. It is the ability of the chameleon to change colors, however, that has led to the figurative use of "chameleon" for someone or something that is quick to change. Such figurative use dates back to at least the late 16th century, as demonstrated by King James VI who, writing in 1586 or 1587, requested "I praye you not to takk me to be a Camelion."
