Coward's work complaint? (3,5)
I believe the answer is:
hay fever
This clue could be a double definition.
'coward's work' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'complaint?' is the second definition.
(medical complaint)
Can you help me to learn more?
(Other definitions for hay fever that I've seen before include "Coward's" , "Pollinosis" , "Rhinitis resulting from an allergic reaction to pollen" , "Coward created this" , "Irritation caused by pollen" .)
