'Wednesday' originates from Old English, specifically the word 'Wōdnesdæg', where 'Wōden' referred to the god Odin and 'dæg' meant 'day'.

'Wōdnesdæg' transformed into the Middle English word 'Wednesdei', and eventually became the modern English word 'Wednesday'.

Initially, it meant 'Odin's day', but over time it evolved into its current meaning of 'the day of the week following Tuesday'.
