Ally; pal (6)
I believe the answer is:
friend
I believe this clue is a double definition.
'ally' is the first definition.
(I know that ally can be written as friend)
'pal' is the second definition.
(I've seen this before)
(Other definitions for friend that I've seen before include "Supporter of cause" , "Pal, mate" , "Colleague" , "Comrade for finder" , "Member of religious society" .)
