The World is a proper noun for the planet Earth envisioned from an anthropocentric or human worldview, as a place inhabited by human beings. It is often used to signify the sum of human experience and history, or the 'human condition' in general. There were approximately 6.5 billion (or 6500 million) people living on the Earth as of February 2006.
Especially in a metaphysical context, World may refer to everything that constitutes reality and the Universe: see World (philosophy).
Etymology
In English, world may be parsed as rooted in a compound of the obsolete words were, "man", and eld, "age"; thus, its etymology may be semantically rendered as "age or life of man".
Usage
World' distinguishes the entire planet or population from any particular country or region: world affairs are those which pertain not just to one place but to the whole world, and world history is a field of history which examines events from a global (rather than a national or a regional) perspective. Earth, on the other hand, refers to the planet as a physical entity, and distinguishes it from other planets and physical objects.
'World' can also be used attributively, as an adjective, to mean 'global', 'relating to the whole world', forming usages such as World community. See World (adjective).
By extension, a 'world' may refer to any planet or heavenly body, especially when it is thought of as inhabited.
'World', when qualified, can also refer to a particular domain of human experience.

- The New World is a part of the world discovered or colonized by Europeans later than other parts; it usually refers to the American continents or to Australia. Native Americans and Native Australians tend to dislike this usage. For them America and Australia are not new. Their ancestors have lived there since time immemorial. The Old World refers, by contrast, to the continents of Europe, Asia and north Africa.
