Burmese is a Tibeto-Burman language spoken in Myanmar, where it is the official language, lingua franca, and the native language of the Bamar, the country's largest ethnic group. Burmese dialects are also spoken by the indigenous tribes in Bangladesh's Chittagong Hill Tracts, India's Mizoram, Manipur, Tripura states and the Burmese diaspora. The Constitution of Myanmar officially refers to it as the Myanmar language in English, though most English speakers continue to refer to the language as Burmese, after Burma—a name with co-official status until 1989. Burmese is the most widely-spoken language in the country, where it serves as the lingua franca. In 2019, Burmese was spoken by 42.9 million people globally, including by 32.9 million speakers as a first language, and an additional 10 million speakers as a second language. A 2023 World Bank survey found that 80% of the country's population speaks Burmese.
