Assented (7)
I believe the answer is:
acceded
'assented' is the definition.
('accede' can be a synonym of 'assent')
This is all the clue.
(Other definitions for acceded that I've seen before include "Agreed to demand" , "'Agreed, acquiesced (7)'" , "Consented to" , "Assented" , "Yielded to another's wishes" .)
