Did You Know?
Since "nonchalant" comes ultimately from Latin words meaning "not" and "be warm," it's no surprise that the word is all about keeping one's cool. The French word nonchalant, which we borrowed around 1734, has essentially the same meaning as our English word and was derived in Old French from a verb, "nonchaloir," which meant "to disregard." "Nonchaloir" in turn combines the negative "non-" with "chaloir," which means "to concern" and comes from the Latin calēre ("to be warm"). "Unconcerned" is one synonym of "nonchalant," along with "casual," "complacent," and "insouciant."
