Coerced (6)
I believe the answer is:
forced
'coerced' is the definition.
('force' can be a synonym of 'coerce')
This is all the clue.
(Other definitions for forced that I've seen before include "Compelled, made to do something" , "Compelled, made to obey" , "Strained, unnatural" , "Compelled or obliged" , "compulsory" .)
