Luwian language
ancient language
Luwian was the language of the Luwian people. It is ordered under the Anatolian branch of the Indo-European languages. It died around 600 BCE. Linguists believe that it had two laryngeal consonants inherited from Indo-European, because their cuneiform writing had two symbols that represent laryngeal sounds.
