Artist from Catalonia (4)
I believe the answer is:
dali
'artist from catalonia' 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 "Surrealist Spanish painter, d. 1989" , "Tree" , "Controversial painter" , "Salvador . . . . was great Spanish surrealist painter" , "Salvador --, twentieth century Spanish surrealist painter" .)
