Capital punishment? (4)
I believe this clue is a double definition.
'capital' is the first definition.
(thesaurus)
'punishment' is the second definition.
(fine is a kind of punishment)
(Other definitions for fine that I've seen before include "Acceptable - punishment" , "Excellent kind of monetary penalty" , "Unclouded as the money penalty" , "Dry and sunny" , "Suitable" .)
'capital punishment' is the definition.
(synonyms)
This is the entire clue.
(Another definition for death penalty that I've seen is " Capital punishment".)
