Partially seen from behind, sculptor I mistook for painter (4)
I believe the answer is:
miro
'sculptor i mistook for painter' is the definition.
I can't tell whether this definition defines the answer.
'partially seen from behind' is the wordplay.
'partially seen' becomes 'mir' (I can't explain this - if you can you should give a lot more credence to this answer).
'from' becomes 'o' (I've seen this in other clues).
'behind' says to put letters next to each other.
'mir'+'o'='MIRO'
Can you help me to learn more?
(Other definitions for miro that I've seen before include "Joan -, twentieth century Spanish surrealist painter" , "He painted" , "Joan --, Spanish artist" , "Catalan artist" .)
