Drunkenly berates nun in front of unknown seasonal donor (6,5)
I believe the answer is:
easter bunny
'seasonal donor' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'drunkenly berates nun in front of unknown' is the wordplay.
I cannot really see how this works, but
an anagram of 'berates' is 'easterb' which is located in the answer.
an anagram of 'nun' is 'unn' which is located in the answer.
'unknown' could be 'y' (algebra) and 'y' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for easter bunny that I've seen is " Popular symbol of the oldest Christian festival".)
