composed of people from or at home in many parts of the world; especially not provincial in attitudes or interests; "his cosmopolitan benevolence impartially extended to all races and to all creeds"- T.B. Macaulay; "the ancient and cosmopolitan societies of Syria and Egypt"; "that queer, cosmopolitan, rather sinister crowd found around the Marseilles docks"
The word cosmopolitan describes an environment where many cultures from around the world coexist; or a person whose perspective reflects exposure to a variety of cultures. It may also have the weaker senses of "worldly" or "sophisticated".
Cosmopolitan is a magazine for women, sometimes referred to as "Cosmo", which has been published for more than a century. It began as a family magazine, launched in 1886 by Schlicht & Field as The Cosmopolitan.
