Set location (5)
I believe the answer is:
place
I believe this clue is a double definition.
'set' is the first definition.
(placing is a kind of setting)
'location' is the second definition.
(place is a kind of location)
(Other definitions for place that I've seen before include "Situation" , "Locus" , "vacancy" , "Location; put" , "Locate" .)
