Order, for the fellow, fruit (7)
I believe the answer is:
mandate
'order' is the definition.
(I know that mandate is a type of order)
'fellow fruit' is the wordplay.
'fellow' becomes 'man' (fellow can mean a man).
'fruit' becomes 'date' (date is a kind of fruit).
'man'+'date'='MANDATE'
'for the' acts as a link.
(Other definitions for mandate that I've seen before include "Authority to do something" , "approval" , "Decree" , "Official command; commission" , "Social appointment for male - or authority given" .)
