Friday: [OE] Friday was named for Frigg, in Scandinavian mythology the wife of Odin and goddess of married love and of the hearth (Frigg, or in Old English Frīg, is thought to have come from prehistoric Germanic *frijaz ‘noble’, source of English free). ‘Frigg’s day’ was a direct adaptation of Latin Veneris dies ‘Venus’s day’ (whence French vendredi ‘Friday’), which in turn was based on Greek Aphrodítēs hēméra ‘Aphrodite’s day’. => free[Friday etymology, Friday origin, 英语词源]
