Animosity resulting from malaise, perhaps (3,7)
I believe the answer is:
ill feeling
'animosity' is the definition.
(thesaurus)
'resulting from malaise perhaps' is the wordplay.
I cannot quite understand how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ill feeling that I've seen before include "Sickly sensation" , "bad blood" .)
