MOWSS/maʊs/

A small rodent with a pointed nose and a long thin tail.

The small mouse has a pointed snout and long, slender tail.

A single small house mouse in three-quarter side view, with a pointed snout, rounded ears, delicate paws and a long slender tail, beside a few grains that establish its small size.
Etymology

Old English mus already named the rodent and could also mean an arm muscle. That second use reflects an old comparison between a moving muscle and a little mouse.
