Live with increasingly feral fox (8)
I believe the answer is:
bewilder
'fox' is the definition.
(synonyms)
'live with increasingly feral' is the wordplay.
'live' becomes 'be' (synonyms).
'with' says to put letters next to each other.
'increasingly feral' becomes 'wilder' (I can't explain this - if you can you should believe this answer much more).
'be'+'wilder'='BEWILDER'
Can you help me to learn more?
(Other definitions for bewilder that I've seen before include "Confuse utterly" , "Confuse - perplex" , "Perplex the wild beer" , "fox" , "Confuse, puzzle" .)
