Absolutely – freezing (5-4)
I believe the answer is:
stone-cold
I believe this is a double definition.
'absolutely' is the first definition.
(I've seen this in another clue)
'freezing' is the second definition.
(I've seen this before)
(Other definitions for stone-cold that I've seen before include "Having lost all warmth" , "Absolutely without heat" , "At a low temperature" .)
