'dialogue' originates from Greek, specifically the word 'dialogos,' where 'dia-' meant 'through' and 'logos' meant 'speech or reason.'

'dialogos' transformed into the Latin word 'dialogus,' and eventually became the modern English word 'dialogue' through Old French 'dialoge.'

Initially, it meant 'a conversation between two or more people,' and this meaning has largely remained the same in modern usage.
