Etymology

Origin of world

First recorded before 900; Middle English; Old English world, weorold; cognate with Dutch wereld, German Welt, Old Norse verǫld, all from (unnattested) Germanic wer-ald- literally, “age of man” ( see virile ( def. ), werewolf ( def. ), old ( def. )


Explanation

The noun world usually refers to the earth, including both the planet itself and the organisms that live on it. If you say, "I want to get out and see the world," you want to go everywhere and see everything. World can also mean someone's individual experiences — your world changed when you got a cat — or one particular region or group, like an actor famous throughout the Spanish-speaking world. While today you can use the words world and earth interchangeably, world originally meant just human experience; the Old English wer, or man, plus ald, or age, together formed weralt: the age of man.
