Yielded to (8)
I believe the answer is:
indulged
'yielded to' is the definition.
('indulge' can be a synonym of 'yield to')
This is all the clue.
(Other definitions for indulged that I've seen before include "Gratified the wishes of" , "Pampered" , "Satisfied (an interest)" , "Gratified a wish, allowed to have" .)
