This video was recorded by Yusuf Hidayat in Ciamis, Indonesia. Sundanese is spoken by as many as a 40 million people, primarily on the Indonesian islands of Java and Sumatra, where it is recognized as a regional language by the provincial governments of Banten and West Java. A member of the Austronesian language family, Sundanese bears relation in grammar, vocabulary, and genealogy to more than 1,000 mother tongues across South Asia and the Pacific, including Madurese, Balinese, and Indonesian. It has been a literary language for centuries, having developed a unique writing system by the 14th century CE. Today, Sundanese speakers write the language with a modern variant of this script, sometimes in conjunction with the Javanese script and Latin alphabet.
