Control, restrict (8)
I believe the answer is:
restrain
I believe this is a double definition.
'control' is the first definition.
(I know that control is a more specific form of restrain)
'restrict' is the second definition.
(I know that restrain is a more specific form of restrict)
(Other definitions for restrain that I've seen before include "Keep under control" , "bottle up" , "Keep back" , "use handcuffs?" , "Hold back, tether" .)
