Anger after tavern shelling (7)
I believe the answer is:
barrage
'shelling' is the definition.
(synonyms)
'anger after tavern' is the wordplay.
'anger' becomes 'rage' (rage is a kind of anger).
'after' is a charade indicator (letters next to each other).
'tavern' becomes 'bar' (I've seen this before).
'rage' after 'bar' is 'BARRAGE'.
(Other definitions for barrage that I've seen before include "Long bust of fire - dam" , "number of shots" , "Assault" , "Continuous fusillade or a torrent of questions" , "a lot of shells" .)
