Move to the outskirts (4)
I believe the answer is:
edge
I believe this is a double definition.
'move' is the first definition.
(thesaurus)
'the outskirts' is the second definition.
(I've seen this in another clue)
'to' is the link.
(Other definitions for edge that I've seen before include "The part farthest from the middle" , "Border - advantage" , "Inch; border" , "small advantage" , "Keenness" .)
