Where badger may be failing test (4)
I believe the answer is:
sett
'where badger may' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'failing test' is the wordplay.
'failing' is an anagram indicator (a failed spelling of the word).
'test' with letters rearranged gives 'SETT'.
'be' acts as a link.
Can you help me to learn more?
(Other definitions for sett that I've seen before include "Badgers' lair" , "Badger's earth" , "beastly accommodation" , "Badger's home" , "Badger's residence" .)
