European authority replacing oxygen in spirits and sweet drinks (8)
I believe the answer is:
liqueurs
'sweet drinks' is the definition.
(liqueurs are sweet drinks)
'european authority replacing oxygen in spirits' is the wordplay.
I cannot quite understand how this works, but
'european' could be 'eur' (abbreviation for European) and 'eur' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for liqueurs that I've seen before include "Sweet after-dinner alcoholic drinks" , "Strong, highly flavoured drinks" , "Strong sweet alcoholic spirits for after meals" , "Tasty alcoholic post-dinner drinks" , "Sweetened spirits" .)
