Pound and Euro lines (7)
I believe the answer is:
rondeau
'pound' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'and euro lines' is the wordplay.
'and euro' can be anagrammed to 'RONDEAU'.
Though, I am not clear how this is indicated.
Can you help me to learn more?
(Other definitions for rondeau that I've seen before include "set of lines" , "Type of poem" , "Form of verse by Swinburne" , "Sort of poem" , "Style of poem" .)
