Eau de Cologne, say (7)
I believe the answer is:
perfume
'eau de cologne say' is the definition.
(I know that cologne is a type of Perfume)
This is all the clue.
(Other definitions for perfume that I've seen before include "sweet-smelling liquid" , "Fragrance, scent" , "What's pleasant-smelling" , "Fragrant toiletry" , "Aroma" .)
