Enclose, confine (3,2)
I believe the answer is:
hem in
I believe this is a double definition.
'enclose' is the first definition.
(thesaurus)
'confine' is the second definition.
(to hem someone in is to confine them)
(Other definitions for hem in that I've seen before include "Encircle" , "Border" , "Confine" .)
