Hunk and date aboard toboggan wrapped up warm (8)
I believe the answer is:
swaddled
'wrapped up warm' is the definition.
I can't tell whether this defines the answer.
'hunk and date aboard toboggan' is the wordplay.
'hunk' becomes 'wad' (I can't explain this - if you can you should believe this answer much more).
'and' says to put letters next to each other.
'date' becomes 'd' (common abbreviation eg in DOB, date of birth).
'aboard' is an insertion indicator.
'toboggan' becomes 'sled' (toboggan is a type of sled).
'wad'+'d'='wadd'
'wadd' inserted into 'sled' is 'SWADDLED'.
Can you help me to learn more?
(Other definitions for swaddled that I've seen before include "well wrapped up" , "Tightly wrapped up" , "Restricted by material" , "Wrapped in cloth" .)
