Etymology and usage
The English word world comes from the Old English weorold (-uld), weorld, worold (-uld, -eld), a compound of wer "man" and eld "age," which thus means roughly "Age of Man." The Old English is a reflex of the Common Germanic wira-alđiz, also reflected in Old Saxon werold, Old High German weralt, Old Frisian warld and Old Norse verǫld (whence the Icelandic veröld).
