The German word 'Arbeit', work, descends from Porto-Germanic *arbaidiz, which meant hardship or suffering. Going a couple of thousand years further back in time, the ancestor of arbaidiz was Porto-Indo-European *h₃órbʰos, which mean orphan or slave. 'Orphan' has the same root via Latin. So Arbeit <> orphan: distant cousins. 'Arbeit' did have a relative in Old English too: it was 'earfoþe', difficult, hard
