Hair
Definition:
(n.) The collection or mass of filaments growing from the skin of an animal, and forming a covering for a part of the head or for any part or the whole of the body.
(n.) One the above-mentioned filaments, consisting, in invertebrate animals, of a long, tubular part which is free and flexible, and a bulbous root imbedded in the skin.
(n.) Hair (human or animal) used for various purposes; as, hair for stuffing cushions.
