'dine' originates from Old French, specifically the word 'disner,' where 'dis-' meant 'apart' and 'jejunare' meant 'to fast.'

'disner' transformed into the Middle English word 'dinen,' and eventually became the modern English word 'dine.'

Initially, it meant 'to break a fast,' but over time it evolved into its current meaning of 'to eat dinner or the main meal of the day.'
