The English word Kazakh, meaning a member of the Kazakh people. It might originate from the Turkic word verb qaz-, 'to wander', reflecting the Kazakhs' nomadic culture. The term 'Cossack' is of the same origin. The Persian suffix -stan means "land" or "place of", so Kazakhstan (Kazakh: Қазақстан, romanized: Qazaqstan) can be literally translated as "land of the wanderers".
In Turko-Persian sources, the term Özbek-Qazaq first appeared during the middle of the 16th century, in the Tarikh-i-Rashidi by Mirza Muhammad Haidar Dughlat, a Chagatayid prince of Kashmir. In this manuscript, the author locates Kazakh in the eastern part of Desht-i Qipchaq. According to Vasily Bartold, the Kazakhs likely began using that name during the 15th century.
Though Kazakh traditionally referred only to ethnic Kazakhs, including those living in China, Russia, Turkey, Uzbekistan and other neighbouring countries, the term is increasingly being used to refer to any inhabitant of Kazakhstan, including residents of other ethnicities.
