Relinquish product (5)
I believe the answer is:
yield
I believe this clue is a double definition.
'relinquish' is the first definition.
(thesaurus)
'product' is the second definition.
(yield is a kind of product)
(Other definitions for yield that I've seen before include "Income" , "bow" , "Produce, provide" , "Stop defending" , "return of financial investment" .)
