Plural of cosmopolis; multiple cities or societies where people from different nations and cultures live together as world citizens.
From cosmopolis + -es (plural suffix). The plural form maintains the Greek construction while simply indicating more than one cosmopolis.
As cosmopolises multiply globally, each one demonstrates that humans can genuinely live together across ethnic and national lines—Toronto is often called one of the world's most successful cosmopolises precisely because it embraces rather than fights cultural diversity.
