Etymology

Origin of tusk

before 900; Middle English, metathetic variant of tux, Old English, variant of tusc tush ²; cognate with Old Frisian tusk; akin to tooth

Explanation

A tusk is the long, pointed tooth seen on some animals, such as elephants, walruses, or hogs. Animals that have tusks can use them for protection against predators. Tusk rhymes with dusk. A tusk is a tooth that grows outward from an animal's mouth. How is a tusk different from a fang? Fangs are used to seize prey and bite and tear. Tusks, on the other hand, are used for defense and even as tools for digging or, in the cause of the walrus, for holding steady while on ice.
