Badger refers to any of several carnivorous mammals which belongs to the Mustelidae family. It comes from Middle English bageard made up from bage (referring to a token or distinctive mark, sign, or emblem) of uncertain etymology though either from Anglo-Norman bage or Latin bagia (sign, emblem), perhaps named for the white mark on its forehead, combined with the suffix -ard.
Badger is also an English surname, either originating as an occupational name for someone who made or supplied bags or as a nickname for someone who behaved or resembled a badger. Another possible origin of the surname is that it’s made up of Old English personal name Bæcg combined with ofer (ridge, border, edge).
As a word, badger is used to mean “to pester or to annoy persistently”.
Origin: Latin, Proto-Indo-European
