Zazaki is spoken by about 1,5 million people in parts of central and eastern Turkey. It belongs to the Iranian branch of the Indo-Iranian language family and has quite a lot in common with such languages as Gilaki and Talyshi.
Zazaki was first written in 1850 using a version of the Arabic alphabet. In the 1980s use of the Latin alphabet to write Zazaki became popular among the Zazaki diaspora in Sweden, France and Germany. Since then a number of books and magazines have been published in Zazaki, and there are some radio and TV programmes in the language.
