Give in or give out (5)
I believe the answer is:
yield
This clue is a double definition.
'give in' is the first definition.
('yield' can be a synonym of 'give in')
'give out' is the second definition.
(I've seen this before)
'or' acts as a link.
(Other definitions for yield that I've seen before include "Amount of product" , "Stop defending" , "bow" , "Abandon" , "profits" .)
