Natural — born (6)
I believe the answer is:
innate
I believe this is a double definition.
'natural' is the first definition.
(I know that natural can be written as innate)
'born' is the second definition.
(I know that born can be written as innate)
(Other definitions for innate that I've seen before include "Congenital" , "Inherent or inborn" , "Have tea in inn - it's natural" , "Bred in the bone, one might say" , "instinctive ..." .)
