Black and white burrower (6)
I believe the answer is:
badger
'black and white burrower' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for badger that I've seen before include "One tagging" , "who pins an emblem on?" , "Black and white animal called Brock" , "A mammal; harry" , "Carnivore - pester" .)
