Contribute to unlimited grant for artist (9)
I believe the answer is:
donatello
'for artist' is the definition.
(I've seen this before)
'contribute to unlimited grant' is the wordplay.
'contribute to' becomes 'donate' (I am not sure about this - if you are sure you should believe this answer much more).
'unlimited' indicates the central letters (remove the limits/outer letters).
'grant' becomes 'allow' (synonyms).
The central letters of 'allow' are 'llo'.
'donate'+'llo'='DONATELLO'
Can you help me to learn more?
(Other definitions for donatello that I've seen before include "Italian sculptor" , "Italian artist" , "Famous Florentine sculptor" , "C 15 Florentine sculptor" , "Chipper" .)
