Did You Know?
Pachydermos in Greek means literally "having thick skin" (figuratively, it means "dull" or "stupid"). It's from pachys, meaning "thick," and derma, meaning "skin." In the late 1700s the French naturalist Georges Cuvier adapted the Greek term as pachyderme and used it for any one of a whole assemblage of hoofed animals having thickish skin: elephants, hippopotamuses, rhinoceroses, tapirs, horses, pigs, and more. English speakers learned the word from French in the early 1800s. The adjective pachydermatous means "of or relating to the pachyderms" or "thickened" (referring to skin). Not too surprisingly, it also means "callous" or "insensitive" (somewhat unfairly to elephants, which are actually known to be rather sensitive).

"Each month, as Nandi bounds closer to her first birthday on Aug. 20, we will keep you in the know on what’s new with this precious pachyderm’s progress." - Johanna Willett, Arizona Daily Star, June 18, 2015
