Friendly nature (4)
I believe the answer is:
kind
I believe this is a double definition.
'friendly' is the first definition.
('kind' can be a synonym of 'friendly')
'nature' is the second definition.
(thesaurus)
(Other definitions for kind that I've seen before include "Gentle and friendly" , "Friendly - type" , "Character, nature" , "Tender-hearted" , "Sort of compassionate" .)
