Not new, unknown word of unknown meaning (5)
I believe the answer is:
nonny
I'm afraid I can't even guess how this answer relates to the clue.
Can you help me to learn more?
(Another definition for nonny that I've seen is " What hid obscenity".)
I've seen this clue in The Sunday Times and The Times.
Want a hint initially instead of a full solution?
