Ends in incurable society (9)
I believe the answer is:
terminals
'ends' is the definition.
(terminal or final things)
'in incurable society' is the wordplay.
I cannot really understand how this works, but
'in' is within the answer.
'society' could be 's' (common abbreviation in names of organisations) and 's' 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?
(Another definition for terminals that I've seen is " Tramlines to boundaries".)
