Ancient Bajoran
Ancient Bajoran was the language used by the Bajorans 30,000 years ago, though not easily translatable in the 24th century. Elements of Ancient Bajoran ideograms evolved into the modern Bajoran language. ()

Captain Benjamin Sisko could recognize Ancient Bajoran, but not read or speak it. In 2375, Sisko came into possession of a locket that belonged to Sarah Sisko with an Ancient Bajoran inscription on the back that read "Orb of the Emissary". Later, a would-be Bajoran Assassin spoke a Cult of the Pah-wraiths chant in Ancient Bajoran before stabbing Sisko. ()
