'ambrosian' originates from the Greek word 'ambrosios,' where 'ambrosia' meant 'immortal' or 'divine food.'

'ambrosios' transformed into the Latin word 'ambrosius,' and eventually became the modern English word 'ambrosian.'

Initially, it meant 'divine or immortal,' but over time it evolved into its current meaning of 'exceptionally pleasing to taste or smell.'
