Scope of morning section (5)
I believe the answer is:
ambit
'scope' is the definition.
('ambit' can be a synonym of 'scope')
'morning section' is the wordplay.
'morning' becomes 'am'.
'section' becomes 'bit' (I've seen this in other clues**).
'am'+'bit'='AMBIT'
'of' acts as a link.
(Other definitions for ambit that I've seen before include "Compass, scope" , "Range, scope" , "Circuit, compass" , "Limits" , "Range - surroundings" .)
