New Yorker’s got rid of cold (4)
I believe the answer is:
iced
'cold' is the definition.
(similar in meaning)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for iced that I've seen before include "despatched to American underworld" , "Dispatched" , "Decorated with sugary mixture" , "Chilled - killed" , "Core; card; organ" .)
