Batza is a member of the Shalaise Language Family and a sister language of Shaelic, Cendlese, Vessic, and Suash, having originated on the island of Shaelia. It is spoken primarily in the Nænre Batzara (“Holding of Batza”) and in the southern regions of Nænre Cesaera (“Holding of Cesae”) in the northern part of the country. According to the 2011 Census, Batza is the primary language of just under 50,000 people in the country, primarily in Batza. With the beginning of the unification of the country in 1811 and the addition of Batza in 1875, the language has been supplanted by Shaelic in both government and home use. UNESCO has Batza listed as “definitely endangered”.
