It’s cold in winter, as one snuggles into the fur (10)
I believe the answer is:
seasonable
'it's cold in winter as one snuggles into the fur' is the definition.
I can't judge whether this definition defines the answer.
'it's cold in winter as one snuggles into the fur' is the wordplay.
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'cold in winter as one snuggles' becomes 'ason' (I can't explain this - if you can you should believe this answer much more).
'into' means one lot of letters goes inside another.
'the fur' becomes 'sable' (sable is a kind of fur).
'e'+'ason'='eason'
'eason' placed inside 'sable' is 'SEASONABLE'.
Can you help me to learn more?
(Other definitions for seasonable that I've seen before include "welcome" , "Appropriate for the time of year" .)
