A f-fortune to distribute (5)
I believe the answer is:
allot
'distribute' is the definition.
(allotting is a kind of distributing)
'a f-fortune' is the wordplay.
'f-fortune' becomes 'llot' ('lot' said with a stammer like 'fortune' was; 'lot' can be a synonym of 'fortune').
'a'+'llot'='ALLOT'
'to' is the link.
(Other definitions for allot that I've seen before include "split up" , "Give, apportion" , "budget" , "Give as a share, or a task to be done" , "Assign or distribute" .)
