Give up and give in (5)
I believe the answer is:
yield
I believe this is a double definition.
'give up' is the first definition.
(thesaurus)
'give in' is the second definition.
('yield' can be a synonym of 'give in')
'and' acts as a link.
(Other definitions for yield that I've seen before include "Give way; produce" , "Submit, give way" , "Relinquish" , "Profit" , "earnings" .)
