Capital punishment? (4)

There are a few possibilities for this:

Which length description are you looking for?:

12 5,7

fine

I believe this clue is a double definition.

'capital' is the first definition.
(thesaurus)

'punishment' is the second definition.

(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" .)

I've seen this clue in The Telegraph, The Globe and Mail, The Guardian, The Irish News and The Sun.
