Go out together to get fruit (4)
I believe the answer is:
date
I believe this clue is a double definition.
'go out together' is the first definition.
(I've seen this in another clue)
'fruit' is the second definition.
(date is a kind of fruit)
'to get' acts as a link.
(Other definitions for date that I've seen before include "Stoned fruit" , "Assignation; fruit" , "sell-by, for example" , "Day, month and year" , "For example, sell by" .)
