A child wrapped in fur in the winter, perhaps (8)
I believe the answer is:
seasonal
'winter perhaps' is the definition.
'seasonal' can be an answer for 'winter' (thesaurus). I'm not certain of the 'perhaps' bit.
'a child wrapped in fur' is the wordplay.
'child' becomes 'son' (son is a kind of child).
'wrapped in' means one lot of letters goes inside another.
'fur' becomes 'seal' (seal is a kind of fur).
'a'+'son'='ason'
'ason' put inside 'seal' is 'SEASONAL'.
'in the' acts as a link.
Can you help me to learn more?
(Other definitions for seasonal that I've seen before include "specifically for Christmas period, say" , "not wanted all year" , "Appropriate to the time of year" , "For a particular period" , "Like an Easter egg" .)
