...notice acquiescence (11)
I believe the answer is:
resignation
I believe this is a double definition.
'notice' is the first definition.
(thesaurus)
'acquiescence' is the second definition.
(thesaurus)
(Other definitions for resignation that I've seen before include "acquiescence" , "Calm acceptance" , "Acceptance of the inevitable" , "Notice" , "Giving up job" .)
