Cold type from summit in Nice heading off to Cork
I believe the answer is:
icecap
'cold type from summit' is the definition.
I can't tell whether this definition defines the answer.
'nice heading off to cork' is the wordplay.
'heading off' means to remove the first letter.
'to cork' becomes 'cap' (I can't explain this - if you can you should believe this answer much more).
'nice' with its initial letter taken away is 'ice'.
'ice'+'cap'='ICECAP'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for icecap that I've seen before include "Permanent polar covering" , "frozen peak" , "hard water area" , "Frozen top of mountain etc" , "Polar expanse" .)
