World Places By Hartmut Bardtke

'World' can also be used attributively, to mean 'global', 'relating to the whole world', forming usages such as World community.
By extension, a 'world' may refer to any planet or heavenly body, especially when it is thought of as inhabited, especially in the context of science fiction or futurology.
'World', in original sense, when qualified, can also refer to a particular domain of human experience.
The world of work describes paid work and the pursuit of career, in all its social aspects, to distinguish it from home life and academic study.
