Scope of the section pre-lunch? (5)
I believe the answer is:
ambit
'scope' is the definition.
(synonyms)
'section pre-lunch?' is the wordplay.
I cannot really see how this works, but
'section' could be 'bit' (both can mean part) and 'bit' is present in the answer.
The remaining letters 'am' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'of the' is the link.
Can you help me to learn more?
(Other definitions for ambit that I've seen before include "Circumference" , "Scope or confines" , "Scope, extent, or bounds of something" , "Range - surroundings" , "Range, scope" .)
