'allophylian' originates from Greek, specifically the word 'allophylos,' where 'allo-' meant 'other' and 'phylos' meant 'tribe or race.'

'allophylos' transformed into the Latin word 'allophylus,' and eventually became the modern English word 'allophylian.'

Initially, it meant 'belonging to another tribe or race,' but over time it evolved into its current meaning of 'relating to non-Indo-European peoples or languages.'
