Smell from ram or alpaca returned (5)
I believe the answer is:
aroma
'smell' is the definition.
(aroma is a kind of smell)
'from ram or alpaca returned' is the wordplay.
'from' indicates the answer is hidden within the clue.
'returned' is a reversal indicator.
'amora' can be found hidden inside 'ram or alpaca'.
'amora' back-to-front is 'AROMA'.
(Other definitions for aroma that I've seen before include "Distinctive scent" , "Odour, mostly pleasing" , "Savour" , "Distinctive smell" , "Nose" .)
