Mush dialect is a Western Armenian dialect formerly spoken in the city of Mush (Muş) and the historic region of Taron, in present-day eastern Turkey. As a result of the extermination of the native Armenian population during the genocide of 1915, the dialect is almost completely extinct today with only several thousand native speakers in a number of villages in Armenia and three Armenian-populated villages in the Samtskhe-Javakheti province of Georgia.

Armenian is an Indo-European language and the sole member of an independent branch of that language family. It is the native language of the Armenian people and the official language of Armenia. Historically spoken in the Armenian highlands, today Armenian is widely spoken throughout the Armenian diaspora. Armenian is written in its own writing system, the Armenian alphabet, introduced in 405 AD by the canonized saint Mesrop Mashtots. The estimated number of Armenian speakers worldwide is between five and seven million.
