Languages in Indonesia Indonesia is a country with multicultural condition. We live with differences like race, religion, ethnic, language, culture, tradition, etc. In general, each region have their own local language. For example like my city, Palembang. In informal condition like talking with friends, buying something at traditional market, and etc, people usually use Palembang language. In the formal condition or institution like school, office, and etc, we use Indonesian, as the national language and unifying the nation. Why I could say Indonesian as the nation unifying language?Hmm if I am not mistaken, It's because most of Indonesian people comunicate with others outside from that group by using Indonesian except if the person understand that group language :D. There are a lot of local languages in Indonesia. For example at my home, my mother is come from Bangka Island, so she usually speak with my father and her family from Bangka in Bangka language. My parents usually speak with their children in Palembang language. but because I often hear their conversation, so I know the meaning of some Bangka language words ^^. Another example at my office, there is my co worker is come from Sekayu city. Sekayu is still a part of South Sumatera province. So she can speak Sekayu language. Because she is working at Palembang, she can speak Palembang Language too. I usually comunicate with my co workers in Palembang language. Another co workers at my office is Java descant. So they can speak Javanese.
