Binds round the neck (4)
I believe the answer is:
ties
'binds' is the definition.
('tie' can be a synonym of 'bind')
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for ties that I've seen before include "Drawn games" , "Binds with male neckwear" , "Attaches, knots" , "obligations" , "Links" .)
