Synonym discussion

Sense: noun/1

Wool, fleece, fur, and hair all refer to coverings on animal bodies, but they differ in scope and use. Wool specifically describes the soft, thick undercoat of sheep and similar animals (goats, llamas) that people shear and use for textiles. Fleece refers to the wool coat of a single sheep after shearing — it is wool, but the term emphasises the whole collected mass in one piece. Fur is a broader term covering the dense hair of many mammals (cats, bears, rabbits) and is usually used for clothing or decoration rather than spinning into thread. Hair is the most general term and includes the fine strands found on humans and animals. In everyday British English, people say "a wool jumper" but not "a fleece jumper" (fleece now more often means a synthetic jacket), while in American English "wool sweater" is standard.

Etymology

Indo-EuropeanGermanicOld EnglishEnglish

The word wool comes from Old English wull, which goes back to a shared Germanic root wullō. This root can be traced further to the ancient Indo-European word wel-, meaning 'to pull or tear', referring to the act of plucking hair from animals. The word has been used for the fleece of sheep since before the 12th century, and its meaning later expanded to include the thread and cloth made from this material.
