Definite cure (8)

I believe the answer is:

specific

This clue is a double definition.

'definite' is the first definition.
(I've seen this in another clue)

'cure' is the second definition.
(thesaurus)

(Other definitions for specific that I've seen before include "Precise, not vague" , "Particular, distinct" , "Clearly defined or identified" , "Relating uniquely to a subject; precise, clear" , "Clear and exact" .)

I've seen this clue in The Globe and Mail and The Irish News.
