Scope or bounds (5)
I believe the answer is:
ambit
This clue is a double definition.
'scope' is the first definition.
(synonyms)
'bounds' is the second definition.
(I've seen this in another clue)
(Other definitions for ambit that I've seen before include "Circumference" , "Limits" , "Range, scope" , "Compass, scope" , "Scope or circuit" .)
