A Short History
The word "badger", originally applied to the European badger (Meles meles), comes from earlier bageard (16th century), presumably referring to the white mark borne like a badge on its forehead. Similarly, a now archaic synonym was bauson 'badger' (1375), a variant of bausond 'striped, piebald', from Old French bausant, baucent 'id.'.
The less common name brock (Old English: brocc), (Scots: brock) is a Celtic loanword (cf. Gaelic broc and Welsh broch, from Proto-Celtic *brokkos) meaning "grey". The Proto-Germanic term was *þahsuz (cf. German Dachs, Dutch das, Norwegian svintoks; Early Modern English dasse), probably from the PIE root *tek'- "to construct," so the badger would have been named after its digging of setts (tunnels); the Germanic term *þahsuz became taxus or taxō, -ōnis in Latin glosses, replacing mēlēs ("marten" or "badger"), and from these words the common Romance terms for the animal evolved (Italian tasso, French taisson—blaireau is now more common—Catalan toixó, Spanish tejón, Portuguese texugo).

A male European badger is a boar, a female is a sow, and a young badger is a cub. However, in North America the young are usually called kits, while the terms male and female are generally used for adults. A collective name suggested for a group of colonial badgers is a cete, but badger colonies are more often called clans. A badger's home is called a sett.
