A wild binge may be only human (5)
I believe the answer is:
being
'only human' is the definition.
'being' can be an answer for 'human' (I've seen this in another clue). I'm unsure of the 'only' bit.
'a wild binge' is the wordplay.
'a wild' is an anagram indicator.
'binge' is an anagram of 'BEING'.
'may be' is the link.
Can you help me to learn more?
(Other definitions for being that I've seen before include "See 9" , "Existing" , "A living creature" , "A matter of 9 in the play" , "Living thing" .)
