Finish with chemical peeling confined to one area (7)
I believe the answer is:
endemic
'area' is the definition.
The answer and definition can be both states of affairs as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'finish with chemical peeling confined to one' is the wordplay.
I cannot quite understand how this works, but
'finish' could be 'end' (synonyms) and 'end' is present in the answer.
'one' could be 'i' (Roman numeral) and 'i' 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 endemic that I've seen before include "Native to (med.)" , "constantly present in the locality" , "Confined to a particular area" , "Widely prevalent" , "(Of a disease) prevalent in a group or area" .)
