The trouble mum has with another woman? (6)
I believe the answer is:
malady
'the trouble' is the definition.
The answer and definition can be both states of affairs as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'mum has with another woman?' is the wordplay.
I cannot quite understand how this works, but
'mum' could be 'ma' (ma can mean mother) and 'ma' is found within the answer.
'woman?' could be 'lady' (lady is a kind of woman) and 'lady' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for malady that I've seen before include "Complaint" , "Afflication" , "Disease, ailment" , "Sickness or disease" , "Illness or disease" .)
