Perfume obtained with small coin (5)
I believe the answer is:
scent
'perfume' is the definition.
(I know that perfume can be written as scent)
'with small coin' is the wordplay.
'with' is a charade indicator (letters next to each other).
'small' becomes 's' (abbreviation - e.g. clothes size).
'coin' becomes 'cent' (cent is a kind of coin).
's' next to 'cent' is 'SCENT'.
'obtained' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for scent that I've seen before include "Fragrance" , "Get wind of" , "Distinctive smell" , "Clue" , "Pleasant smell" .)
