Fix, as a fight (3)
I believe the answer is:
rig
'fix as a fight' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rig that I've seen before include "Kit" , "Fit with sails and tackling" , "Apparatus; (boat's) sails" , "set-up" , "Set up; equipment" .)
