Picture an ancient Greek naming a strange little reptile: not a dragon, not a snake, but a “lion of the ground.” That is χαμαιλέων, built from khamai, “on the earth,” and leōn, “lion”—a wonderfully grand name for an animal that creeps along branches and shoots out a tongue like a living tape measure. The “lion” may have been suggested by the prominent crest on some chameleons, though Wiktionary records an even older possibility: a Greek calque of Akkadian “lion of the ground.” English first encountered the creature as Middle English camelion, and the missing h returned in the early 18th century when scholars gave the spelling a Latin makeover. By the 1580s, the lizard had lent its talent for changing appearance to people, producing the figurative sense of a social chameleon; in 2003, physicists Justin Khoury and Amanda Weltman borrowed the word again for a hypothetical environment-sensitive particle. Remember it this way: a chameleon is a lion only if the ground—and sometimes the crowd—changes beneath it.
