Without affectation as expected (9)
I believe the answer is:
naturally
I believe this is a double definition.
'without affectation' is the first definition.
(I've seen this before)
'as expected' is the second definition.
(thesaurus)
(Other definitions for naturally that I've seen before include "Without artificial help" , "it goes without saying" , "As a matter of course" , "Occurring normally, not artificially" , "without medical assistance" .)
