What is a badgers nickname?

The name badger is possibly derived from the French Word blaireau being used in both senses. But more likely, the term comes from the French Word bêcheur (digger), introduced during William the Conqueror's reign. An older term for "badger" is brock (Old English brocc), a Celtic loanWord (Gaelic broc, Welsh broch, from Proto-Celtic *brokko). The Proto-Germanic term was *þahsu- (German Dachs), probably from the PIE root *tek'- "to construct," so that the badger would have been named after its digging of setts (tunnels).

A male badger is a boar, a female a sow and a young badger is a cub. The collective name for a group of badgers is a clan, colony, or cete.
