'gastronome' originates from French, specifically the word 'gastronome', where 'gastro-' meant 'stomach' and '-nome' meant 'law or knowledge'.

'gastronome' changed from the French word 'gastronome' and eventually became the modern English word 'gastronome'.

Initially, it meant 'a person knowledgeable about food', and this meaning has largely remained the same in modern usage.
