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."

chameleon

noun
cha·​me·​leon kə-ˈmēl-yən How to pronounce chameleon (audio)
1
: any of various lizards that can vary the color of their skin
2
: a person who easily or frequently changes attitude or purpose
Etymology

Middle English chamelion "chameleon," from early French chamelion (same meaning), from Latin chamaeleon (same meaning), from Greek chamaileōn, from chamai "on the ground" and leōn "lion"

Word Origin
The chameleon of the Old World has a fierce look. The Greeks called it chamaileōn, combining their words chamai, meaning "on the ground," and leōn "lion." It may be that the upright ridge of skin behind the head of many of these lizards reminded them of the lion's mane. The Romans borrowed the Greek word for this little creature, and the French later took the Latin word. For a long time after the word was borrowed into Middle English, it was spelled chamelion, with the ending like our modern word lion. But later writers who knew the form of the word in ancient Greek and Latin changed the spelling to chameleon, to match the original form. From its use as the name of a creature able to change color with its mood or the temperature, the word came to be used for a person who is changeable.
