Submit return (5)
I believe the answer is:
yield
This clue is a double definition.
'submit' is the first definition.
(thesaurus)
'return' is the second definition.
('yield' can be a synonym of 'return')
(Other definitions for yield that I've seen before include "admit defeat" , "Surrender, give in" , "Bring in -- give up" , "Concede - product" , "Chicken out" .)
