Grasp collar (9)
I believe the answer is:
apprehend
I believe this is a double definition.
'grasp' is the first definition.
('apprehend' can be a synonym of 'grasp')
'collar' is the second definition.
('apprehend' can be a synonym of 'collar')
(Other definitions for apprehend that I've seen before include "Arrest (for a crime)" , "Dread; capture" , "Fearfully anticipate" , "Arrest; perceive" , "Be terribly afraid" .)
