Compensation, alas for Shakespeare, pocketed by two theatres (9)
I believe the answer is:
repayment
'compensation' is the definition.
(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for repayment that I've seen before include "Refund" , "Type of mortgage" , "Money refunded" , "Reimbursement" .)
