Yield, surrender (7)
I believe the answer is:
concede
I believe this is a double definition.
'yield' is the first definition.
(I know that yield can be written as concede)
'surrender' is the second definition.
(I know that concede is a type of surrender)
(Other definitions for concede that I've seen before include "Admit; yield" , "Make admission" , "Admit (defeat in match)" , "Yield; grant" , "Admit something is true" .)
