Kazakh or Qazak is Kazakhstan's official language. It's widely used in Central Asia, with over 13 million native speakers. Because it's a sub-branch of the Turkic language family, it's closely related to other spoken languages such as Azerbaijani and Turkish. It's a minority language in prefectures and provinces in China and Mongolia. Ethnic Kazakhs in Russia and Germany are also among its speakers.
Compared to English and Spanish, Kazakh is a less widespread language. An excellent incentive to learn it is for professional reasons. The ability to communicate effectively and maintain harmonious relationships in Kazakhstan is essential when engaging in business, tourism, and culture.
