Armenian is actually the official language of Armenia, and it is estimated to have 6.7 million native speakers.
The language is unique in many ways. Unlike many languages based on the Greek or Latin alphabet, the Armenian alphabet was actually invented by a man called Mesrop Mashtots in 405 AD. It was created so the Bible could be translated into a written language for the Armenian people.
The language also has some distinctive sounds that distinguish it from other Indo-European languages. These are voiceless sounds, and rather than the lungs being used to push air out, it is the vocal cords that do this instead.
