Etymology
Origin of rodent
1825–35; < New Latin Rodentia Rodentia
Explanation
A rodent is any of an order of (usually) small, furry, gnawing mammals whose two pairs of front teeth — one pair in the upper jaw, and one in the lower — never stop growing. Mice, rats, and squirrels are rodents, and so are larger mammals like beavers, porcupines, and capybaras. The term rodent sometimes has a negative connotation, as people associate some rodents, especially mice and rats, with carrying diseases or being pests. But many people keep rodents, such as gerbils and hamsters, as pets. And rodents are an important part of ecosystems. Beavers build dams that create wetland habitats for fish and other creatures, and small rodents like mice are an important food source for some birds, snakes, and mammals. In traditional Chinese culture, rats are associated with cleverness, adaptability, and prosperity.
