Distinctive smells (6)
I believe the answer is:
odours
'distinctive smells' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for odours that I've seen before include "Aromas, pungencies" , "Smells, good or bad" , "Distinctive smells" , "Smells, redolences" , "Smells of any kind" .)
