Other than Javanese, Sundanese is another local language that has influenced Indonesian's vocabulary, albeit to a lesser extent.
This is attributed to the fact that the capital, Jakarta, was formerly a part of West Java, a province which, together with Banten before it too was divided, constitutes the Pasundan (Sundanese world), the most significant non-Javanese region in an otherwise Javanese-dominated Java island.
Conversely, many words of Malay-Indonesian origin have also been borrowed into English.
The Indonesian language has absorbed many loanwords from other languages, including Sanskrit, Tamil, Hindi, Arabic, Persian, Portuguese, Dutch, Chinese and other Austronesian languages.
Indonesian differs from the form of Malay used in Malaysia in a number of respects, primarily due to the different influences both languages experienced and also due to the fact that the majority of Indonesians speak another language as their mother tongue.
Most of its speakers are the inhabitants of Jakarta, and its influence upon Indonesian is attributed to its frequent usage in Indonesian mass media, including radio and television.
Its status as a "hip" language by other aspects of Indonesian society is another contributing factor as well.
