Italian song I adore you, having renounced love for drink (3,5)
I believe the answer is:
tia maria
'drink' is the definition.
(tia maria is an alcoholic drink)
'italian song i adore you having renounced love' is the wordplay.
I cannot really see how this works, but
'italian' could be 'i' (abbreviation for Italian) and 'i' is found in the answer.
'song' could be 'aria' (piece of music in an opera) and 'aria' is found within the answer.
'i' could be 'a' and 'a' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for tia maria that I've seen before include "Rum-based coffee liqueur" , "After-dinner liqueur" , "Coffee-flavour liqueur" , "drink is served?" , "Coffee-flavoured rum drink" .)
