Beholden (to) (7)
I believe the answer is:
obliged
'beholden to' is the definition.
(thesaurus)
This is all the clue.
(Other definitions for obliged that I've seen before include "Morally or legally bound (to do something)" , "Did favours - compelled" , "Constrained" , "Made bound (to do something)" , "Did favour to, or coerced" .)
