Etymology

Origin of glabrous

1630–40; < Latin glabr- (stem of glaber ) smooth, hairless + -ous

Explanation

The term glabrous describes surfaces that are smooth and free of hair, fur, or other types of fuzz. While most mammals are covered with hair or fur, some mammals, like adult dolphins, have glabrous skin. You might describe a shiny apple or a naked mole-rat as glabrous. In botany, a leaf without any tiny hairs or fuzz is considered glabrous. Similarly, a person with a freshly shaved head has a glabrous scalp. The word comes from the Latin word glaber, meaning "smooth or bald." This term is often used in both botany and anatomy to describe organic surfaces that are completely smooth and hairless.
