Compensate for first of redundancies, with me busier, somehow (9)
I believe the answer is:
reimburse
'compensate' is the definition.
(reimbursing is a kind of compensating)
'first of redundancies with me busier somehow' is the wordplay.
'first of' says to take the initial letters.
'with' says to put letters next to each other.
'somehow' indicates an anagram.
The first letter of 'redundancies' is 'r'.
'me'+'busier'='mebusier'
'mebusier' with letters rearranged gives 'eimburse'.
'r'+'eimburse'='REIMBURSE'
'for' is the link.
(Other definitions for reimburse that I've seen before include "Repay - reuse brim" , "Repay a person who has spent or lost money" , "Compensate for money already spent" , "Repay (a sum of money)" , "Financially compensate" .)
