Telugu script (Telugu: తెలుగు లిపి, romanized: Telugu lipi), an abugida from the Brahmic family of scripts, is used to write the Telugu language, a Dravidian language spoken in the Indian states of Andhra Pradesh and Telangana as well as several other neighbouring states. It is one of the official scripts of the Indian Republic. The Telugu script is also widely used for writing Sanskrit texts and to some extent the Gondi language. It gained prominence during the Eastern Chalukyas also known as Vengi Chalukya era. It shares extensive similarities with the Kannada script, as both of them evolved from the Bhattiprolu and Kadamba scripts of the Brahmi family. In 2008, the Telugu language was given the status of a Classical Language of India, in recognition of its rich history and heritage.
