As a matter of interest, say, gives up (6)
I believe the answer is:
yields
'gives up' is the definition.
(yield can mean to give up or surrender)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for yields that I've seen before include "Gives way, surrenders" , "Surrenders or produces as harvest" , "Crops or dividends" , "Succumbs" , "Submits" .)
