Armed conflict at the fair after Waugh spoke up (7)
I believe the answer is:
warfare
'armed conflict' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for warfare that I've seen before include "Scraps, too, by the look of it" , "Struggle" , "All-out fighting" , "action" , "Armed contest" .)
