He has earthly possessions (9)
I believe the answer is:
landowner
'he has earthly possessions' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he' is the wordplay.
I cannot really understand how this works, but
'he' could be 'land' and 'land' is located in the answer.
The remaining letters 'owner' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for landowner that I've seen before include "Owner of an area" , "Laird" , "Squire, perhaps" , "One with much property" , "One may have lots of grass" .)
