badger

\ \ [16] The Old English term for a ‘badger’ was brock, a word of Celtic origin, and badger does not begin to appear, somewhat mysteriously, until the early 16th century. The name has never been satisfactorily explained, but perhaps the least implausible explanation is from the word badge, in reference to the white stripes on the animal’s forehead, as if it were wearing a badge (a term originally applied to a distinctive device worn by a knight for purposes of recognition); the early spelling bageard suggests that it may have been formed with the suffix -ard, as in dullard and sluggard. (Badge itself is of even more obscure origin; it first turns up in Middle English, in the mid 14th century.) Other early terms for the badger were bauson (14th– 18th centuries), from Old French bausen, and grey (15th–17th centuries).
