He may go from one side to the other (8)
I believe the answer is:
renegade
'he may go from one side to the other' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he may go from' is the wordplay.
I cannot really see how this works, but
'he' could be 'rene' and 'rene' is present in the answer.
'from' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
The remaining letters 'gad' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for renegade that I've seen before include "disloyal type" , "Perfidious" , "Dare Gene to become a rebel" , "not someone true to the cause" , "Apostate" .)
