Control, hold in check (8)
I believe the answer is:
restrain
This clue is a double definition.
'control' is the first definition.
(I know that control is a more specific form of the action restrain)
'hold in check' is the second definition.
(thesaurus)
(Other definitions for restrain that I've seen before include "Keep back" , "Manacle" , "Control - check" , "bottle up" , "In arrest (anagram)" .)
