Javanese language is the spoken language of people in central and eastern part of island of Java, in Indonesia. According to Ethnologue, it is spoken by approximately 75,500,000 people.

The Javanese language is part of the Malayo-Polynesian (or Austronesian) family of languages, and is therefore related to Bahasa Indonesia and Malay. Many speakers of Javanese also speak Bahasa Indonesia, which they use primarily for official and business purposes.

Today, it is generally written using the Latin alphabet, but formerly used an alphabet Kavi, in the Saka era, derived from the Devanagari script (see Brahmi) of India. It has also been written using the Arabic alphabet, one thousand years after Kavi.
