Fresh euros sold out (9)
I believe the answer is:
odourless
'fresh' is the definition.
Both the answer and definition are adjectives.
Perhaps there's a link between them I don't understand?
'euros sold out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'euros'+'sold'='eurossold'
'eurossold' anagrammed gives 'ODOURLESS'.
Can you help me to learn more?
(Other definitions for odourless that I've seen before include "not using scent" , "Without so much as a whiff" , "Without smell" , "descriptive of clean air" , "not raising a stink" .)
