Etymology

It is borrowed from Ancient Greek διάλογος (diálogos, “conversation”), related to διαλέγομαι (dialégomai, “to converse”), from διά (diá, “across”) and λέγω (légō, “to speak”).[2][1][3] The TLL dates it from Cicero, who sometimes writes it in Greek.[4][5] Isidore defines it as a discussion of two or more persons.[4]

Earliest recorded meaning

The OLD's earliest citations are from Cicero, of a discussion and of a written dialogue.[2] Köbler dates Cicero 81–43 BC.[6]

Semantic evolution

It meant a discussion, a dispute, and a literary work in dialogue form, a philosophical dialogue, as in Cicero and Quintilian.[2][5][7]

In Ecclesiastical Latin it meant a dialogue or conversation.[8] British Medieval Latin used it for Gregory the Great's Dialogues and for dramatic dialogue.[9] It survives in Italian dialogo and French dialogue, and English dialogue came about 1200, “a literary work in the form of a conversation”.[1][3]
