Wool is the textile fiber obtained from sheep and certain other animals, including cashmere from goats, mohair from goats, qiviut from muskoxen, angora from rabbits, and other types of wool from camelids.
Wool has several qualities that distinguish it from hair or fur: it is crimped, it is elastic, and it grows in staples (clusters). In the United States the term wool is usually restricted to describing the fibrous protein derived from the specialized skin cells called follicles in sheep, although in the UK it may be used of any long curling fiber such as wood wool, wire wool, etc.
Famous quotes containing the words sheep and/or wool:
“I too have been in the underworld, as was Odysseus, and I will often be there again; not only sheep have I sacrificed so as to be able to speak with a few dead souls, but neither have I spared my own blood as well.”
—Friedrich Nietzsche (18441900)
“After all, the wool of a black sheep is just as warm.”
—Ernest Lehman (b. 1920)
