Bantenese language, Western Sundanese language or Western Sundanese dialect is a dialect of Sundanese language spoken by the Bantenese and Sundanese native to Banten and the western side of Bogor Regency. The western Bogor area comprises the Jasinga Raya region, which covers Jasinga, Cigudeg, Tenjo, Nanggung, Parungpanjang, Sukajaya districts and also the northwestern parts of Sukabumi Regency. The Bantenese language is the lingua franca of the Kasepuhan Ciptagelar traditional community in Cisolok subdistrict, and the Kasepuhan Banten Kidul traditional community.
The regional government of Banten is currently making a significant approach to preserve this dialect through a news program entitled Beja ti Lembur, which was aired by the regional CTV Banten network in Bantenese language.
The Bantenese language in general does not recognize registers of language, due to the fact that Banten was never under the rule or influence of the Mataram Sultanate, differed from the Priangan dialect spoken in the Parahyangan region. This has caused the Bantenese language to be seen as a language that is still closely related to the old Sundanese language.
Today, the Bantenese language is categorized as a western dialect of Sundanese language. This dialect is generally spoken mostly in the southern region of Banten, which are Lebak (including Cilangkahan region), and Pandeglang Regency (including Caringin and Cibaliung). In the northern Serang Regency, this language is used daily by the people of Ciomas, Pabuaran, Padarincang, Cinangka, Baros, Petir, Cikeusal, Kopo, Cikande, Pamarayan and parts of Anyar subdistrict. This dialect is also used by Sundanese transmigrants in Central Lampung Regency, Lampung.
In Serang Regency, Bantenese language and Bantenese Javanese are both used daily by the people of Anyar, Mancak, Waringinkurung, Taktakan, Cipocok Jaya, Walantaka, as well as Kragilan subdistrict. This dialect is also used in some parts of Tangerang Regency, especially in its southern, southwestern, midwest and northern parts, as well as in cities of Tangerang and South Tangerang.
