'aerophagia' originates from Greek, specifically the word 'aerophagia,' where 'aero-' meant 'air' and '-phagia' meant 'eating or swallowing.'

'aerophagia' has remained largely unchanged from its Greek origins, maintaining its meaning related to the swallowing of air.

Initially, it meant 'swallowing air,' and this meaning has largely remained the same in modern usage.
