'gastronomic' originates from Greek, specifically the word 'gastronomikos,' where 'gastro-' meant 'stomach' and '-nomikos' meant 'pertaining to law or custom.'

'gastronomikos' transformed into the French word 'gastronomique,' and eventually became the modern English word 'gastronomic.'

Initially, it meant 'pertaining to the laws of the stomach,' but over time it evolved into its current meaning of 'relating to the art or science of good eating.'
