Chuck fruit (5)
I believe the answer is:
berry
I believe this clue is a double definition.
'chuck' is the first definition.
(musician Chuck Berry)
'fruit' is the second definition.
(I know that berry is a type of fruit)
(Other definitions for berry that I've seen before include "Romeo's family" , "Smal pulpy fruit" , "Word linking black or blue" , "Small edible fruit" , "Small soft fruit" .)
