Day for fruit (4)
I believe the answer is:
date
This clue is a double definition.
'day' is the first definition.
(I know that day can be written as date)
'for fruit' is the second definition.
(date is a kind of fruit)
(Other definitions for date that I've seen before include "Girlfriend perhaps" , "A social appointment - check calendar" , "Appointment - fruit of palm" , "eg 1588" , "Go out with" .)
