- C-3PO: "Perhaps I can be of assistance, your highness. As you know, I am fluent in over six million forms of communication. I could transmit the coordinates to Commander Antilles in Boordist or Vaathkree trade language for example—"

- C-3PO: "Of course… Oh dear…"
- ―Han Solo, Princess Leia and C-3PO talk at the battle of Filve[src]
Vaathkree trade language was an obscure, possibly extinct language that was one of C-3PO's six million forms of communication. He suggested its use as a form of code to use to talk to Wedge Antilles at the Battle of Filve, before Han Solo pointed out that Wedge could not speak Vaathkree trade language.
