Pay back Polish over in French city with tablet (9)
I believe the answer is:
reimburse
'pay back' is the definition.
(I've seen this before)
'polish over in french city with tablet' is the wordplay.
'polish over' becomes 'bur' (I can't explain this - if you can you should believe this answer much more).
'in' indicates putting letters inside.
'french city' becomes 'reims' (city in France).
'with' is a charade indicator (letters next to each other).
'tablet' becomes 'e' (E can mean ecstasy or an ecstasy tablet).
'bur' going within 'reims' is 'reimburs'.
'reimburs'+'e'='REIMBURSE'
Can you help me to learn more?
(Other definitions for reimburse that I've seen before include "Pay back any expenses incurred" , "Pay back (e.g. expenses)" , "Repay a person who has spent or lost money" , "Repay (a sum of money)" , "Financially compensate" .)
