Rogue back in Oxford, say (4)
I believe the answer is:
heel
This clue could be a double definition.
'rogue' is the first definition.
(I've seen this before)
'back in oxford say' is the second definition.
'heel' can be an answer for 'back' (thesaurus). I'm not certain of the 'in oxford say' bit.
Can you help me to learn more?
(Other definitions for heel that I've seen before include "Hindu loincloth" , "horrible person" , "site of Achilles' downfall?" , "Bounder; part of foot" , "unpleasant type" .)
