Seasonal issue produced by whimsical tosser for Spooner (3,5)
I believe the answer is:
hay fever
'spooner' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for hay fever that I've seen before include "Coward play" , "Allergy caused by pollen, dust etc" , "Pollinosis" , "The result of an allergic reaction to pollen" , "Allergic affliction" .)
