Give up, as land
I believe the answer is:
cede
'give up as land' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cede that I've seen before include "Give up (eg, power)" , "Give up rights or possession" , "Yield or give up to another" , "Surrender, give up" , "Relinquish control of" .)
