lông nhung
Definition
- Noun:
- Villus (plural: villi): A tiny, hair-like projection, especially on a mucous membrane. In biology and anatomy, this term most commonly refers to the intestinal villi, which are microscopic finger-like projections lining the small intestine that increase its surface area for nutrient absorption.
- Velvet (texture): A soft, smooth fabric or surface that has a short, dense pile, resembling fine fur or down. This meaning describes a texture similar to the fine, soft hairs of certain animals or plants.

Notes on Usage
- In scientific contexts (biology, medicine), "lông nhung" almost exclusively refers to villi. The primary example is lông nhung ruột (intestinal villi).
- In everyday language describing texture, "lông nhung" is used metaphorically to describe any surface that is as soft and fine as velvet or fine fur. For the fabric itself, the word "nhung" is more common.
