Instinctively, naturally (8)
I believe the answer is:
innately
I believe this is a double definition.
'instinctively' is the first definition.
(I've seen this before)
'naturally' is the second definition.
(thesaurus)
(Other definitions for innately that I've seen before include "Naturally, inherently" , "from birth" , "Inherently, instinctively" , "How kids react" .)
