Definitions

2. Characterized by a surface adorned with fine, hair-like extensions that enhance texture and play a role in biological functions and interactions
3. Having a surface densely clothed with fine, soft, hair-like structures that influence texture and function in living organisms

Etymology: "Villous" comes from Latin "villus," meaning "shaggy hair" or a tuft of hair, and the English adjective is a straightforward formation from that noun with the "-ous" suffix meaning "full of" or "having the qualities of." Something villous is therefore covered in soft, shaggy hairs, the same image the Latin noun conjured. The word's usefulness lies in its precision. In anatomy and botany, the hairs in question are often far too fine to call hair in everyday terms: the tiny projections lining the small intestine, for instance, are described as villous, as are the surfaces of certain leaves and seeds. The Latin root gave the word its shaggy, tufted sense, and the adjective preserves that image while narrowing it to the microscopic textures that scientists needed to name.
