Sweet smell, it's apparently returning somewhat (8)
I believe the answer is:
pastille
'sweet' is the definition.
(pastille is a kind of sweet)
'smell it's apparently returning somewhat' is the wordplay.
'somewhat' says the answer is hidden in the clue.
'returning' says the letters should be written backwards.
'ellitsap' is hidden in the letters of 'smell its apparently'.
'ellitsap' reversed gives 'PASTILLE'.
(Other definitions for pastille that I've seen before include "Lozenge, to soothe the throat perhaps" , "Flavoured or medicated lozenge" , "something for a sore throat" , "List plea for the small sweet" , "Cough lozenge" .)
