Language spoken on the other side of the world is music to Eliza's ears (6)
I believe the answer is:
strine
'language' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see a link between them that I don't see?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for strine that I've seen before include "Australian lingo" , "vernacular" , "Aussie English" .)
