Submit a return (5)
I believe the answer is:
yield
This clue is a double definition.
'submit' is the first definition.
(I know that submit is a kind of the yield)
'a return' is the second definition.
(I know that return can be written as yield)
(Other definitions for yield that I've seen before include "profits" , "volte-face" , "bow" , "Render" , "Generate (return)" .)
