Candidate coming with no explosive energy (7)
I believe the answer is:
nominee
'candidate' is the definition.
(I know that candidate can be written as nominee)
'coming with no explosive energy' is the wordplay.
'coming with' is a charade indicator (letters next to each other).
'explosive' becomes 'mine' (e.g. a landmine).
'energy' becomes 'e' (physics symbol as in E=mc2).
'no' put next to 'mine' is 'nomine'.
'nomine'+'e'='NOMINEE'
(Other definitions for nominee that I've seen before include "One put forward as a candidate" , "His/her name is put forward" , "He's put forward" , "he may shield one" , "One whose name is put forward" .)
