Spots cloak, say, in painting (8)
I believe the answer is:
seascape
'in painting' is the definition.
'seascape' can be an answer for 'painting' (I've seen this before). I am not sure about the 'in' bit.
'spots cloak' is the wordplay.
'spots' becomes 'seas' (I can't explain this - if you can you should believe this answer much more).
'cloak' becomes 'cape' (cape is a kind of cloak).
'seas'+'cape'='SEASCAPE'
'say' acts as a link.
Can you help me to learn more?
(Other definitions for seascape that I've seen before include "Painting - pea cases (anag)" , "rollers" , "Marine view" , "off the coast?" , "Main work" .)
