Our home, dirt (5)
I believe the answer is:
earth
This clue is a double definition.
'our home' is the first definition.
(home of all humanity)
'dirt' is the second definition.
(I've seen this before)
(Other definitions for earth that I've seen before include "Badger's burrow" , "Soil; fox's lair" , "Land" , "Familiar example of 1 Across" , "Dirty hole" .)
