Audibly apprehends person patiently suffering cosmetic procedure (4,3)
I believe the answer is:
nose job
'procedure' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for nose job that I've seen before include "Piece of plastic surgery" , "Facial operation" , "Surgery of the face" , "work for boat race" , "Unfortunately" .)
