Scottish island, reportedly unknown, displays allure (6)
I believe the answer is:
beauty
This clue could be a double definition.
'scottish island' is the first definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'reportedly unknown displays allure' is the second definition.
The definition and answer can be both human attributes as well as being singular nouns.
Maybe you can see an association between them that I can't see?
Can you help me to learn more?
(Other definitions for beauty that I've seen before include "Aesthetic quality" , "very attractive lady" , "` `. . . . . . is only skin-deep' '" , "Very fine specimen" , "Opposite fairy tale characters" .)
