Artist somewhat weird? A little (4)
I believe the answer is:
dali
'artist' is the definition.
(I've seen this before)
'somewhat weird? a little' is the wordplay.
'somewhat' says the answer is hidden in the clue.
'DALI' can be found hidden inside 'weird a little'.
(Other definitions for dali that I've seen before include "Salvador among artists" , "Surrealist Spanish painter, d. 1989" , "Salvador --, twentieth century Spanish surrealist painter" , "Controversial painter" , "Tree" .)
