Grumpiness as a result of some funny ailment? (3,6)
I believe the answer is:
ill humour
'grumpiness' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see a link between them that I can't see?
'some funny ailment?' is the wordplay.
'some funny' becomes 'ill' (eg feeling a bit funny).
'ailment?' becomes 'humour' (I can't justify this - if you can you should give a lot more credence to this answer).
'ill'+'humour'='ILL-HUMOUR'
'as a result of' acts as a link.
Can you help me to learn more?
(Other definitions for ill humour that I've seen before include "bad mood" , "bad temper" , "bad feeling" .)
