'Friday' originates from Old English, specifically the word 'Frīgedæg,' where 'Frīge' referred to the goddess Frigg and 'dæg' meant 'day.'

'Frīgedæg' transformed into the Middle English word 'Fridai,' and eventually became the modern English word 'Friday.'

Initially, it meant 'day of Frigg,' and this meaning has largely remained the same in modern usage.
