Bruiser arranged with me to pay back cash (9)
I believe the answer is:
reimburse
'pay back cash' is the definition.
'reimburse' can be an answer for 'pay' (thesaurus). I'm unsure of the 'back cash' bit.
'bruiser arranged with me' is the wordplay.
'arranged with' indicates an anagram.
'bruiser' anagrammed with 'me' makes 'REIMBURSE'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for reimburse that I've seen before include "refund" , "Compensate for money already spent" , "Repay (a sum of money)" , "Pay back (e.g. expenses)" , "Pay back any expenses incurred" .)
