Crack in the cold, maybe (4)
I believe the answer is:
chap
'crack in the cold maybe' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for chap that I've seen before include "Fellow < makes > crack" , "Cracked skin patch caused by cold" , "Bloke, fellow" , "cove" , "we prefer not to have on hand" .)
