Postpone visit (4)
I believe the answer is:
stay
I believe this clue is a double definition.
'postpone' is the first definition.
(thesaurus)
'visit' is the second definition.
(thesaurus)
(Other definitions for stay that I've seen before include "Abide" , "guy giving > support" , "Remain; guy" , "Remain; brace" , "Stanchion" .)
