Around freezing, I talk nonsense to snowball? (8)
I believe the answer is:
cocktail
'snowball?' is the definition.
(snowball is a type of cocktail)
'around freezing i talk nonsense' is the wordplay.
'around' becomes 'c' (abbreviation for 'circa').
'freezing' becomes 'OC' (zero degrees Celsius).
'nonsense' indicates an anagram.
'i'+'talk'='italk'
'italk' anagrammed gives 'ktail'.
'c'+'oc'+'ktail'='COCKTAIL'
'to' is the link.
(Other definitions for cocktail that I've seen before include "Possibly old-fashioned" , "Screwdriver, for example" , "Manhattan, perhaps" , "snowball?" , "Manhattan, for example" .)
