You may have never seen the fuzzy, pointy-nosed animal called a mole even if you know what a mole is, since it lives underground most of the time.

One mole is the mammal with beady little eyes that burrows underground eating earthworms. This mole doesn't need much oxygen to breathe and has big paws for digging tunnels. Another type of mole is basically a large, sometimes raised freckle on the skin; a third is a spy, especially a double agent who pretends to work for one country while sending secret information to another. The burrowing type of mole comes from an obsolete English word, moldwarp, or "earth thrower."
