Javanese is a Malayo-Polynesian language spoken by the Javanese people from the central and eastern parts of the island of Java, Indonesia. There are also pockets of Javanese speakers on the northern coast of western Java. It is the native language of more than 98 million people. It has several regional dialects and a number of clearly distinct status styles. Its closest relatives are the neighboring languages such as Sundanese, Madurese, and Balinese. Most speakers of Javanese also speak Indonesian for official and commercial purposes as well.
The earliest known writing in Javanese dates from the 4th Century AD, at which time Javanese was written with the Pallava alphabet. Since the Dutch introduced the Latin alphabet to Indonesia in the 19th Century, the Javanese alphabet has gradually been supplanted. Today it is used almost exclusively by scholars and for decoration. Those who can read and write it are held in high esteem.
There are three main dialects of the modern language: Central Javanese, Eastern Javanese, and Western Javanese. These three dialects form a dialect continuum from northern Banten in the extreme west of Java to Banyuwangi Regency in the eastern corner of the island. All Javanese dialects are more or less mutually intelligible.
Central Javanese (Jawa Tengahan) is founded on the speech of Surakarta and to a lesser extent of Yogyakarta. It is considered the most "refined" of the regional variants, and serves as a model for the standard language. Central Javanese is also used in the western part of East Java province. For example, Javanese spoken in the Madiun region (along with Javanese spoken in Blitar, Ponorogo, Pacitan, and Tulungagung, and central parts of Kediri) bears a strong influence of Surakarta Javanese.
Western Javanese (Jawa Kulonan), spoken in the western part of the Central Java province and throughout the West Java province (particularly on the north coast), includes dialects that are distinct for their Sundanese influences. It retains many archaic words.
Eastern Javanese (Jawa Wétanan) speakers range from the eastern banks of Brantas River in Kertosono, and from Nganjuk to Banyuwangi, comprising the majority of the East Java province excluding Madura island. However, the variant has been influenced by Madurese.
