'Diptera' originates from Greek, specifically the word 'δίπτερα' (diptera), where 'di-' meant 'two' and 'pteron' meant 'wing.'

'δίπτερα' transformed into the Latin word 'Diptera,' and eventually became the modern English word 'Diptera.'

Initially, it meant 'two-winged,' and this meaning has largely remained the same in modern usage.
