Gets fixed (4)
I believe the answer is:
sets
'gets fixed' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sets that I've seen before include "Scenery etc. of dramatic productions" , "Scenery etc. of 11 across productions" , "Major divisions of tennis match" , "Hardens" , "Groups of things of the same kind" .)
