Artist is home for a little fruit (6)
I believe the answer is:
raisin
'a little fruit' is the definition.
(a raisin is a small fruit)
'artist is home' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'home' becomes 'in' ('he's home' can mean 'he's in').
'ra'+'is'+'in'='RAISIN'
'for' acts as a link.
(Other definitions for raisin that I've seen before include "Dried red grape" , "Dried grape used in cakes" , "A dried grape used in cake" , "Partially dried grape" , "Fruit for the Christmas cake" .)
