Measure of interest in group of islands, or one (5)
I believe the answer is:
capri
'one' is the definition.
Both the answer and definition are singular nouns.
Perhaps there's an association between them I don't understand?
'measure of interest in group of islands' is the wordplay.
I cannot quite understand how this works, but
'measure' could be 'apr' (Apr is an example) and 'apr' is present in the answer.
'islands' could be 'ci' (Channel Islands) and 'ci' is found within the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'or' is the link.
Can you help me to learn more?
(Other definitions for capri that I've seen before include "Romantic Isle in Bay of Naples" , "Neapolitan isle" , "Romantic and expensive island in Bay of Naples" , "holiday destination" , "Italian isle" .)
