Down to earth like big property owners (6)
I believe the answer is:
landed
'down' is the definition.
Both the answer and definition are adjectives. Perhaps there's a link between them I don't understand?
'earth like big property owners' is the wordplay.
'earth' becomes 'land' (synonyms).
'like big property owners' becomes 'ed' (I can't explain this - if you can you should believe this answer much more).
'land'+'ed'='LANDED'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for landed that I've seen before include "Arrived on shore or ground" , "With grounds" , "Came down to earth" , "Disembarked - owning estates" , "Alit; having estates" .)
