Spanish painter laid out (4)
I believe the answer is:
dali
'spanish painter' is the definition.
(I've seen this in another clue)
'laid out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'laid' anagrammed gives 'DALI'.
(Other definitions for dali that I've seen before include "Salvador . . . . was great Spanish surrealist painter" , "Salvador --, twentieth century Spanish surrealist painter" , "Salvador -, twentieth century artist" , "Tree" , "Salvador among artists" .)
