Taking a liberty (9)
I believe the answer is:
admission
I believe this clue is a double definition.
'taking' is the first definition.
(thesaurus)
'a liberty' is the second definition.
(thesaurus)
(Other definitions for admission that I've seen before include "Entree" , "guilt?" , "Letting in - letting out" , "Acknowledgement < of entry" , "Acknowledgment of the truth of something" .)
