Confine to home (6)
I believe the answer is:
ground
'confine to home' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ground that I've seen before include "Powdered; land" , "crushed into small particles" , "Solid part of the earth's surface" , "reduced to dust" , "Base; reason" .)
