Scope, range (5)
I believe the answer is:
ambit
This clue is a double definition.
'scope' is the first definition.
(synonyms)
'range' is the second definition.
(I know that range can be written as ambit)
(Other definitions for ambit that I've seen before include "Range, scope" , "Circuit, compass" , "round" , "Scope, extent, or bounds of something" , "Limits" .)
