View of the main area small duck circles (8)
I believe the answer is:
seascape
'view of the main' is the definition.
(I've seen this before)
'area small duck circles' is the wordplay.
'area' becomes 'a' (maths abbreviation).
'small' becomes 's' (abbreviation - e.g. clothes size).
'duck' becomes 'escape' (I've seen this before).
'circles' indicates putting letters inside (some letters go round others).
's'+'escape'='sescape'
'a' going inside 'sescape' is 'SEASCAPE'.
(Other definitions for seascape that I've seen before include "work of art" , "off the coast?" , "Marine view" , "Coastal or ocean view" , "View of ocean and sky" .)
