Mizo is a Tibeto-Burman language spoken mainly in the Indian state of Mizoram, where it is the official language and lingua franca. It is the mother tongue of the Mizo people and some members of the Mizo diaspora. Other than Mizoram, it is also spoken in Meghalaya, Manipur, Tripura, and Assam states of India, Sagaing Region and Chin State in Myanmar, and Chittagong Hill Tracts of Bangladesh. It is mainly based on the Lusei dialect but it has also derived many words from its surrounding Mizo clans such as Hmar, Pawi, etc.
