Betawi language

Betawi, also known as Batavian, Jakartanese, Betawi Malay, Batavian Malay, or Jakarta Malay, is the spoken language of the Betawi people in and around Jakarta, Indonesia. The name "Betawi" stems from Batavia, the official name of Jakarta during the era of the Dutch East Indies. A precise number of speakers is difficult to determine due to the vague use of the name.

Linguistically, the traditional dialects as spoken for in-group communication within the Betawi community differ quite significantly from Colloquial Jakarta Indonesian, the vernacular Indonesian variety used as a lingua franca among the diverse urbanites in Greater Jakarta and elsewhere in Indonesia. In modern-day Jakarta and the surrounding area, Betawi and Indonesian are often used in a continuum, with traditional varieties as the basilect and Standard Indonesian as the acrolect. Colloquial Jakarta Indonesian, which sits in the middle, incorporate significant influence not only from Betawi, but also from other languages brought by migrants to Jakarta. According to Uri Tadmor, there is no clear border distinguishing Colloquial Jakarta Indonesian from Betawi language.

While Colloquial Jakartan Indonesian has become the primary lingua franca in Jakarta and enjoys great popularity in Indonesian media, traditional Betawi varieties are seriously endangered, as they are now mostly only spoken by the older generation in some locations on the outskirts of Jakarta, such as Kampung Melayu, Pasar Rebo, Pondok Gede, Ulujami, and Jagakarsa.

There is a significant Chinese community which lives around Tangerang, called Cina Benteng, who have stopped speaking Chinese and now speak a Betawi variant with noticeable Chinese influence, including many Chinese (mostly Hokkien) loanwords.
