Complete range or scope (5)
I believe the answer is:
gamut
This clue is a double definition.
'complete range' is the first definition.
(I've seen this in another clue)
'scope' is the second definition.
(I know that gamut is a type of scope)
(Other definitions for gamut that I've seen before include "Entire scale" , "Entire range" , "Ambit" , "The whole range of, say emotions" , "Compass, scale" .)
