Picked up eau de Cologne perhaps? (5)
I believe the answer is:
odour
I'm afraid I can't even guess how this answer relates to the clue.
Can you help me to learn more?
(Other definitions for odour that I've seen before include "Olfactory sensation" , "Smell; repute" , "Smell, redolence" , "Smell, scent" , "for the nose to detect" .)
