Soil; planet (5)
I believe the answer is:
earth
I believe this is a double definition.
'soil' is the first definition.
(synonyms)
'planet' is the second definition.
(Earth is an example)
(Other definitions for earth that I've seen before include "Soil; fox's lair" , "Badger's burrow" , "Familiar example of 1 Across" , "The 3rd planet from the sun" , "wire" .)
