Osing people in the context of "Banyuwangi"

The Javanese (Javanese: ꦮꦺꦴꦁꦗꦮ, romanized: Wong Jåwå (in the ngoko register), ꦠꦶꦪꦁꦗꦮꦶ, Tiyang Jawi (in the krama register); Indonesian: Orang Jawa) are an Austronesian ethnic group native to the central and eastern part of Java island, which covers most of the administrative areas of the provinces of Central Java, East Java, and Special Region of Yogyakarta. With more than 100 million people, Javanese people are the largest ethnic group in both Indonesia and in Southeast Asia as a whole. Their native language is Javanese, it is the largest of the Austronesian languages in number of native speakers and also the largest regional language in Southeast Asia. As the largest ethnic group in the region, the Javanese have historically dominated the social, political, and cultural landscape of both Indonesia and Southeast Asia.

There are significant numbers of Javanese diaspora outside of central and eastern Java regions, including the other provinces of Indonesia, as well as other countries such as Suriname, Singapore, Malaysia, Egypt, Saudi Arabia, South Africa, Sri Lanka, Yemen and the Netherlands. The Javanese ethnic group has many sub-groups (based on native Javanese community on the island of Java) that can be distinguished based on their characteristics, customs, traditions, dialects, or even their respective ways of life. These include Banyumasan, Cirebonese, Mataram, Osing, and Tenggerese. The majority of the Javanese people identify themselves as Sunni Muslims, with a small minority identifying as Christians and Hindus. With a large global population, the Javanese are considered significant as they are the largest Muslim ethnic group in the Far East and the fifth largest in the world after the Arabs, Bengalis, Punjabis, and Turks.

The Tenggerese people are a sub-ethnic group of Javanese in eastern Java who are centered in the isolated Tengger mountains (Mount Bromo) in the Bromo Tengger Semeru National Park in eastern Java. The majority of the Tenggerese population profess Java Hinduism as their religion. They are the only Javanese ethnic group who have remained Hindu since the Majapahit era after the Osing people, who have been Islamized.

Scattered communities of Tenggerese also exist in the Pasuruan, Probolinggo, Malang, and Lumajang regencies of eastern Java. They are traditionally believed to be the descendants of the legendary Roro Anteng and Joko Seger. The Tenggerese are considered an ethnic sub-group of the Javanese people. Tengger people do not have a caste system. Their traditions are rooted in customs originating from the Majapahit Empire.

The Osing language (Osing: Basa Using; Indonesian: Bahasa Osing), locally known as basa Banyuwangi, is the Modern Javanese dialect of the Osing people of East Java, Indonesia. The Osing dialect uses a special diphthongization (changing the vowel [i] to [ai] and the vowel [u] to [au]) which is not found in any Other Javanese dialects. They are primarily distributed in Banyuwangi Regency, but can also be found in the eastern part of Jember Regency, particularly in districts of Panti and Wuluhan.

Some Osing words have the infix /-y-/ 'ngumbyah', 'kidyang', which are pronounced /ngumbah/ and /kidang/ in standard Javanese, respectively.
