Etymology: Muridae is the scientific name of the family that includes rats and mice, and it is a modern coinage rather than an ancient one. It is formed from "mus" (genitive "muris"), the Latin word for mouse, which is itself the source of the name of the genus Mus, the house mouse. Taxonomists then added the standard family-forming ending "-idae" to the stem, a pattern used across zoology to name families after a type genus. The "-idae" suffix comes from the Greek-derived ending "-idae" used in Latin plural forms, and it signals that the name is a family rather than a single genus or species. Muridae thus means, in effect, "the mouse family." Because the group is very large, with well over a thousand species including the brown rat and the house mouse, the name ended up covering a huge share of living rodent diversity.

Synonyms: mouse family, rodents
