Storm created by anger in pub? (7)
I believe the answer is:
barrage
'storm' is the definition.
(thesaurus)
'by anger in pub?' is the wordplay.
'by' is a charade indicator (letters next to each other).
'anger in' becomes 'rage' (rage is a kind of anger. I am not sure about the 'in' bit.).
'pub?' becomes 'bar' (both are drinking establishments).
'rage' after 'bar' is 'BARRAGE'.
'created' is the link.
(Other definitions for barrage that I've seen before include "number of shots" , "Heavy gunfire" , "Artificial obstruction in a river" , "Onslaught" , "Continuous fusillade or a torrent of questions" .)
