Sophisticated magazine (12)
I believe the answer is:
cosmopolitan
This might be a double definition.
'sophisticated' is the first definition.
(similar in meaning)
'magazine' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
Can you help me to learn more?
(Other definitions for cosmopolitan that I've seen before include "Travelled widely" , "Familiar with different cities and cultures" , "Worldly; cocktail" , "Citizen of the world" , "In a magazine" .)
