Alternative forms[edit]


Formed irregularly from tri- + -dialogus, from Ancient Greek διάλογος (diálogos, conversation, discourse), from διά (diá, through, inter) + λόγος (lógos, speech, oration, discourse), from διαλέγομαι (dialégomai, to converse), from διά (diá) + λέγειν (légein, to speak).

Note that official documents of the European Union use the spelling trilogue (perhaps influenced by the French spelling).


trialogue (plural trialogues)

  1. A discourse or colloquy by three people.
