Sniffed honey in toboggan (7)
I believe the answer is:
smelled
'sniffed' is the definition.
(I've seen this in another clue)
'honey in toboggan' is the wordplay.
'honey' becomes 'mel' (Latin name for honey).
'in' means one lot of letters goes inside another.
'toboggan' becomes 'sled' (toboggan is a type of sled).
'mel' going into 'sled' is 'SMELLED'.
(Other definitions for smelled that I've seen before include "Inhaled odour" , "Suspected" , "Savoured" .)
