Tionese, also called Old Tionese, was formerly the language of Tion. It was eventually replaced by Galactic Basic Standard. By the last centuries of the Galactic Republic, its usage was reduced to designating names with its letter names. Its letters were used by organizations such as the Galactic Empire, which used them to designate its squadrons. Just as the so-called -wing starships were named after the shapes of the letters of the High Galactic alphabet, Lambda-class shuttles somewhat resembled the letter λ.
