I regret raising a complaint (7)
I believe the answer is:
ailment
'complaint' is the definition.
(I know that complaint can be written as ailment)
'i regret raising a' is the wordplay.
I cannot quite understand how this works, but
'i' could be 'me' and 'me' is found in the answer.
'a' is found 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 ailment that I've seen before include "Sickness" , "Physical disorder" , "infirmity" , "Complaint, affliction" , "problem" .)
