means The entirety of human existence, society, and experience — or, more locally, the Earth itself as a physical place to live on.

from Rooted in Old English 'weorold,' a fusion of two older Germanic pieces: something like 'wer' (man, person — the same root survives in 'werewolf,' literally 'man-wolf') and 'ald' (age, meaning old or era). So 'world' originally meant something like 'age of man' — human existence stretched across time — rather than a planet at all. The sense shifted gradually from 'the span of human life' to 'the place where that life happens,' and eventually to the whole Earth and everything on it.
