End of autumn in The Mediterranean on weekend - park and explore what a critic gets to see first! (5,7)
I believe the answer is:
sneak preview
'end of autumn in the mediterranean on weekend' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'park and explore what a critic gets to see first' is the wordplay.
I cannot really see how this works, but
an anagram of 'park' is 'akpr' which is located in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is present in the answer.
'see' could be 'view' ('view' can be a synonym of 'see') and 'view' is found within the answer.
The remaining letters 'see' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for sneak preview that I've seen before include "Test screening before general release" , "Unannounced screening" , "Private screening or viewing of new film etc." , "Public showing of a film before general release" .)
