Fruit of the vine (5)
I believe the answer is:
grape
'fruit of the vine' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for grape that I've seen before include "Green/black fruit" , "Vine fruit" , "Vineyard fruit" , "Pager (anag.)" , "In Elgin rummage about in the dark" .)
