'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.

Initially, it meant 'a conversation between two or more people,' but over time it evolved into its current meaning of 'a written or spoken conversational exchange.'
