'luncheon' originates from the Old English word 'nuncheon,' where 'none' meant 'noon' and 'schench' meant 'drink.'

'nuncheon' transformed into the Middle English word 'luncheon,' and eventually became the modern English word 'luncheon.'

Initially, it meant 'a light meal or drink at noon,' but over time it evolved into its current meaning of 'a formal lunch.'
