Subjugate, put into bondage (7)
I believe the answer is:
enslave
This clue is a double definition.
'subjugate' is the first definition.
(I know that enslave is a kind of subjugate)
'put into bondage' is the second definition.
(I've seen this before)
(Other definitions for enslave that I've seen before include "Force into drudgery" , "Save Len (anag.)" , "Deprive (someone) of liberty" , "Bring into servitude" , "Reduce to subservience" .)
