1590s (as colloguing), presumably from colleague (“to associate”) and French colloque (“secret meeting”), from Latin (English colloquy), possibly influenced by dialogue.
Ultimately from Latin collega (“a partner in office”) + Ancient Greek λόγος (lógos, “speech, oration, discourse”), perhaps partly via Latin loquor (“I speak”).
