Big fight (3)

I believe the answer is:

war

'big fight' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for war that I've seen before include "Large-scale conflict" , "State of armed struggle" , "Major conflict" , "Hostile situation" , "Open hostility" .)

I've seen this clue in The New York Times and The Globe and Mail.
