Explosive anger possibly ends in wild dispute (7)
I believe the answer is:
grenade
'explosive' is the definition.
(I've seen this before)
'anger possibly ends in wild dispute' is the wordplay.
'possibly' is an anagram indicator.
'ends in' says to take the final letters.
The final letters of 'wild dispute' are 'de'.
'anger' anagrammed gives 'grena'.
'grena'+'de'='GRENADE'
(Other definitions for grenade that I've seen before include "Small hand-bomb" , "Pineapple" , "Missile thrown" , "Small explosive that is thrown" , "Handy bomb" .)
