Arrow seen in conflict (7)
I believe the answer is:
quarrel
I believe this is a double definition.
'arrow' is the first definition.
(quarrel is a kind of arrow)
'conflict' is the second definition.
(thesaurus)
'seen in' acts as a link.
(Other definitions for quarrel that I've seen before include "missile" , "Argue toss" , "Row - crossbow arrow" , "Wrangle; crossbow bolt" , "Argument; arrow" .)
