Compared to the Malay language spoken as the native regional language in Sumatra and the Malay peninsula or the standardized version of Malaysian, Indonesian differs profoundly by the large amount of Javanese loanwords incorporated into their already rich vocabulary. This is mostly contributed by Java's position as the center of Indonesian politics, education, and culture, since the capital is located in Jakarta on Java island, albeit in the area where the Javanese are not the majority. The disproportionate number of Javanese that dominate Indonesian politics is reflected by the fact that six out of seven Indonesian presidents have been ethnic Javanese. The result is that the Javanese began to pour their own vocabulary into Indonesian to describes terms and words that do not have exact counterparts in the Malay language. It is also important to note that most of Indonesian's Sanskrit loanwords have been transmitted through Old Javanese, a language whose Sanskrit borrowings number almost 50% of the total vocabulary. Javanese loanwords, unlike those from other native languages, have entered the basic vocabulary of Indonesian to such an extent that, for many, they are no longer perceived to be foreign.
