Crowd upset about a conflict at sea? (3,3)
I believe the answer is:
cod war
'conflict at sea?' is the definition.
'cod war' can be an answer for 'conflict' (I have seen 'maritime conflict' mean 'cod war' so perhaps 'conflict' could also mean 'cod war'). I'm not certain of the 'at sea?' bit.
'crowd upset about a' is the wordplay.
'upset' indicates anagramming the letters.
'about' indicates putting letters inside.
'crowd' with letters rearranged gives 'codwr'.
'codwr' placed around 'a' is 'COD WAR'.
Can you help me to learn more?
(Other definitions for cod war that I've seen before include "rows once around Iceland" , "Net disagreement" , "Conflict over the water" , "fishing dispute" , "maritime conflict" .)
