Indonesian is the official and national language of Indonesia. It is a standardized variety of Malay, an Austronesian language that has been used as a lingua franca in the multilingual Indonesian archipelago for centuries. With over 280 million inhabitants, Indonesia ranks as the fourth most populous nation globally. According to the 2020 census, over 97% of Indonesians are fluent in Indonesian, making it the largest language by number of speakers in Southeast Asia and one of the most widely spoken languages in the world. Indonesian vocabulary has been influenced by various regional languages such as Javanese, Sundanese, Minangkabau, Balinese, Banjarese, and Buginese, as well as by foreign languages such as Arabic, Dutch, Portuguese, and English. Many borrowed words have been adapted to fit the phonetic and grammatical rules of Indonesian, enriching the language and reflecting Indonesia's diverse linguistic heritage.
Malay is an Austronesian language that is an official language of Brunei, Indonesia, Malaysia, and Singapore, and that is also spoken in East Timor and parts of Thailand. Altogether, it is spoken by 290 million people across Maritime Southeast Asia.
In addition to its classical and modern literary form, Malay had various regional dialects established after the rise of the Srivijaya empire in Sumatra, Indonesia. Also, Malay spread through interethnic contact and trade across the south East Asia Archipelago as far as the Philippines. That contact resulted in a lingua franca that was called Bazaar Malay or low Malay and in Malay Melayu Pasar. It is generally believed that Bazaar Malay was a pidgin, influenced by contact among Malay, Hokkien, Portuguese, and Dutch traders.
Indonesian slang vernacular, or Jakarta colloquial speech is a term that subsumes various urban vernacular and non-standard styles of expression used throughout Indonesia that are not necessarily mutually intelligible. Regional slang from the capital of Jakarta, based on Betawi language, is however heavily exposed and promoted in national media, and considered the de facto Indonesian slang. Despite its direct origins, Indonesian slang often differs quite significantly in both vocabulary and grammatical structure from the most standard form of Indonesia's national language. These expressions are neither standardized nor taught in any formal establishments, but rather function in daily discourse, usually in informal settings. Several dictionaries of bahasa gaul has been published. Indonesian speakers regularly mix several regional slangs in their conversations regardless of origin, but depending on the audience and the familiarity level with the listeners.
Betawi people, Batavi, or Batavians, are an Austronesian ethnic group native to the city of Jakarta and its immediate outskirts, as such often described as the inhabitants of the city. They are the descendants of the people who inhabited Batavia from the 17th century onwards.
Mardijker is an extinct Portuguese-based creole of Jakarta. It was the native tongue of the Mardijker people. The language was introduced with the establishment of the Dutch settlement of Batavia ; the Dutch brought in slaves from the colonies they had recently acquired from the Portuguese, and the slaves' Portuguese creole became the lingua franca of the new city. The name is Dutch for "freeman", as the slaves were freed soon after their settlement. The language was replaced by Betawi creole Malay in Batavia by the end of the 18th century, as the Mardijker intermarried and lost their distinct identity. However, around 1670 a group of 150 were moved to what is now the village and suburb of Tugu, where they retained their language, there known as Papiá, until the 1940s.

Indonesia is home to over 700 living languages spoken across its extensive archipelago. This significant linguistic variety constitutes approximately 10% of the world’s total languages, positioning Indonesia as the second most linguistically diverse nation globally, following Papua New Guinea. The majority of these languages belong to the Austronesian language family, prevalent in the western and central regions of Indonesia, including languages such as Acehnese, Sundanese, and Buginese. In contrast, the eastern regions, particularly Papua and the Maluku Islands, are home to over 270 Papuan languages, which are distinct from the Austronesian family and represent a unique linguistic heritage. The language most widely spoken as a native language is Javanese, primarily by the Javanese people in the central and eastern parts of Java Island, as well as across many other islands due to migration.
Palembang, also known as Palembang Malay, is a Malayic variety of the Musi dialect chain primarily spoken in the city of Palembang and nearby lowlands, and also as a lingua franca throughout South Sumatra. Since parts of the region used to be under direct Javanese rule for quite a long time, Palembang is significantly influenced by Javanese, down to its core vocabularies.
