Prizes for promotions about conflict (6)
I believe the answer is:
awards
'prizes' is the definition.
(I know this)
'promotions about conflict' is the wordplay.
'promotions' becomes 'ads' (ad is a kind of promotion).
'about' is an insertion indicator.
'conflict' becomes 'war' (war is a kind of conflict).
'ads' enclosing 'war' is 'AWARDS'.
'for' is the link.
(Other definitions for awards that I've seen before include "Symbols of achievement" , "Gives officially as prizes or penalties" , "Official prizes or payments" , "Prizes or tributes" , "Prizes and presentations" .)
