Selection of fruit that's not been started (5)
I believe the answer is:
range
'selection' is the definition.
(a selection is a range of things)
'fruit that's not been started' is the wordplay.
'fruit' becomes 'orange' (orange is a kind of fruit).
'that's not been started' means to remove the first letter.
'orange' with its first letter taken off is 'RANGE'.
'of' is the link.
(Other definitions for range that I've seen before include "Walk for miles" , "Distance aircraft can travel" , "Limits - scope" , "Place to practise driving" , "testing ground" .)
