Definition

Noun 1. A small carnivorous mammal: The stoat is a species of mustelid (family Mustelidae), closely related to weasels. It is known for its long, slender body, short legs, and distinctive black-tipped tail. 2. A seasonal color morph: Specifically, the term "stoat" refers to the animal when it has its brown summer coat. In winter, the same animal's fur typically turns white (except for the black tail tip) and is then commonly called an ermine.

Usage and Examples

• The stoat is an agile hunter, preying on rabbits and rodents much larger than itself.

• In its summer coat, the animal is known as a stoat; in its white winter coat, it is prized as ermine.

Advanced Usage and Notes

• The distinction between "stoat" and "ermine" is primarily based on the animal's fur color, which changes with the seasons for camouflage. "Stoat" is the general name for the species (), while "ermine" specifically denotes the white winter phase or its fur used in ceremonial robes.
• The black tip on the tail remains throughout the year, which is a key identifying feature.
