Bomb angered revolutionary (7)
I believe the answer is:
grenade
'bomb' is the definition.
(I know that grenade is a type of bomb)
'angered revolutionary' is the wordplay.
'revolutionary' is an anagram indicator.
'angered' anagrammed gives 'GRENADE'.
(Other definitions for grenade that I've seen before include "Hand-thrown explosive" , "Enraged (anag)" , "Missile thrown" , "Small hand-bomb" , "Pineapple" .)
