Pine perhaps missing one award (6)
I believe the answer is:
confer
'award' is the definition.
(conferring is a kind of awarding)
'pine perhaps missing one' is the wordplay.
'pine perhaps' becomes 'conifer' (pine is a kind of conifer).
'missing' is a deletion indicator.
'one' becomes 'i' (Roman numeral).
'conifer' with 'i' taken away is 'CONFER'.
(Other definitions for confer that I've seen before include "Discuss - award" , "Bestow - discuss" , "Have discussions" , "Grant or bestow, say a degree" , "Bestow: consult" .)
