What is the difference between cosmopolitan and metropolitan?

Answer 1

Cosmopolitan means between a lot of different places, and metropolitan means the one city. If you had a person that really seems to live everywhere, you could call them very cosmopolitan. If they really just live in the city, they'd be metropolitan. Cosmopolitan also has a sense of international understanding about it, like the person who knows how they live in Paris and in London... they've been around.

Answer 2

My first inclination is that cosmopolitan is the world, while metropolitan is the city. That is without looking them up in the dictionary.
