Wool
Definition:
(n.) The soft and curled, or crisped, species of hair which grows on sheep and some other animals, and which in fineness sometimes approaches to fur; -- chiefly applied to the fleecy coat of the sheep, which constitutes a most essential material of clothing in all cold and temperate climates.
(n.) Short, thick hair, especially when crisped or curled.
(n.) A sort of pubescence, or a clothing of dense, curling hairs on the surface of certain plants.
Example Sentences:
