Area for repair (5)
I believe the answer is:
patch
I believe this clue is a double definition.
'area' is the first definition.
(patch is a kind of area)
'repair' is the second definition.
(patching is a kind of repairing)
'for' is the link.
(Other definitions for patch that I've seen before include "Piece of material sewn over a hole" , "Mend with extra piece" , "Repair; area" , "Material to cover repair" , "Plot - piece of cloth - period" .)
