Gulf War ending in seaside setting (6)
I believe the answer is:
breach
This clue could be a double definition.
'gulf' is the first definition.
(thesaurus)
'war ending in seaside setting' is the second definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for breach that I've seen before include "Failure to follow the rules" , "Gap in a wall or barrier" , "Gap (in defensive wall)" , "Opening - quarrel" , "'Gap, break or hole (6)'" .)
