Pleasing smell (5)
I believe the answer is:
aroma
'pleasing smell' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aroma that I've seen before include "Redolence" , "Agreeable odour" , "Scent - smell" , "A pleasant smell as of food" , "Distinctive scent" .)
