The soft, woolly layer of fur found beneath the outer coat of certain animals, particularly sheep.

Conversation

I just learned that sheep have this thing called underwool.

Really? What is it exactly?

It's the soft woolly undercoat that keeps them warm.

That makes sense! No wonder they look so cozy.

Synonyms & Antonyms

Root Explanation

Underwool → It is formed from "under" (from Old English "under", meaning beneath or below) and "wool" (from Old English "wull", meaning the hair of sheep or similar animals). The word "underwool" refers to the fine, soft wool that lies beneath the coarser outer layer of fleece.

Memory Tip

Think of wool that is found 'beneath' the outer layer — 'under' means beneath, and 'wool' refers to the soft hair of sheep.
