Spanish surrealist (4)
I believe the answer is:
dali
'spanish surrealist' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for dali that I've seen before include "Salvador among artists" , "Salvador --, twentieth century Spanish surrealist painter" , "Salvador -, twentieth century artist" , "Salvador . . . . was great Spanish surrealist painter" , "Controversial painter" .)
