A gnawing mammal of an order that includes rats, mice, squirrels, and beavers, characterized by constantly growing incisors.

Rodent is a scientific classification, but in domestic contexts, it almost always refers to mice or rats acting as pests.

The story behind the word. Derived from the Latin verb rodere, which means 'to gnaw.' The term was introduced into scientific classification in the early 19th century to describe mammals characterized by their continuously growing, sharp incisors used for chewing through hard materials.
