Range, ambit (5)
I believe the answer is:
scope
This clue is a double definition.
'range' is the first definition.
(I know that range can be written as scope)
'ambit' is the second definition.

(Other definitions for scope that I've seen before include "Ambit, compass" , "The range of something, say an inquiry" , "Extent or reach" , "Range of view" , "Field" .)
