- "You've learned Old Alderaanian?"
"Not exactly—but I've picked up enough to make some sense of what I'm collecting."
- ―Qui-Gon Jinn and Obi-Wan Kenobi
Old Alderaanian was a language spoken on the planet Alderaan in ancient times. When Obi-Wan Kenobi was still a Padawan, his Jedi Master Qui-Gon Jinn had him study prophecies written in ancient languages, including Old Alderaanian. A language that looked similar to Old Alderaanian was found by Dez Rydan on Amaxine Station.
