trialogue

Meaning

Noun

• A discourse or colloquy by three people.

Origin

• Formed irregularly from tri- + -dialogus, from Ancient Greek διάλογος ("conversation, discourse"), from διά + λόγος, from διαλέγομαι, from διά + λέγειν.
• Note that official documents of the European Union use the spelling trilogue (perhaps influenced by the French spelling).
