Bound to believe what one hears? (7)
I believe the answer is:
trussed
'bound' is the definition.
('truss' can be a synonym of 'bind')
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for trussed that I've seen before include "Secured" , "Tied up" , "Bundled up" , "Dusters (anag) - bound" , "with restrictions on members" .)
