Delivering fruit precisely (5)
I believe the answer is:
plumb
'precisely' is the definition.
(plumb can mean exactly or precisely)
'delivering fruit' is the wordplay.
'delivering' indicates a 'sounds like' (homophone) clue (I've seen 'delivered' mean this (delivered verbally)).
'fruit' becomes 'plum' (plum is a kind of fruit).
'plum' is a homophone of 'PLUMB'.
(Other definitions for plumb that I've seen before include "Exactly - in a vertical line" , "Exactly - . . . . . in the middle" , "True" , "Test alignment" , "Take soundings at sea" .)
