Last to leave platform after bringing in student artist (4)
I believe the answer is:
dali
'artist' is the definition.
(Salvador Dali)
'last to leave platform after bringing in student' is the wordplay.
I cannot really understand how this works, but
'student' could be 'l' (as in L-plates for learner drivers) and 'l' is found in the answer.
The remaining letters 'dai' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for dali that I've seen before include "Salvador --, twentieth century Spanish surrealist painter" , "Salvador among artists" , "Salvador . . . . was great Spanish surrealist painter" , "Salvador -, twentieth century artist" , "Surrealist Spanish painter, d. 1989" .)
