Delay use outside America (7)
I believe the answer is:
suspend
'delay' is the definition.
(thesaurus)
'use outside america' is the wordplay.
'use' becomes 'spend' (spending is a kind of using**).
'outside' means one lot of letters goes inside another.
'america' becomes 'us' (abbreviation for the United States).
'spend' enclosing 'us' is 'SUSPEND'.
(Other definitions for suspend that I've seen before include "Stay" , "Carry out hanging" , "Delay" , "Hang freely" , "Temporarily debar" .)
