Veteran audibly shuffled cards (3,4)
I believe the answer is:
old maid
'veteran audibly shuffled cards' is the definition.
I can't judge whether this defines the answer.
'veteran audibly' is the wordplay.
'veteran' becomes 'old' (veteran can mean old or former).
'audibly' becomes 'maid' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'old'+'maid'='OLD MAID'
Can you help me to learn more?
(Other definitions for old maid that I've seen before include "Excessively cautious person" , "Fusspot; card game" , "Miss" , "game of cards" , "never taken from the shelf?" .)
