A huge number of languages are spoken on the 6 000 inhabited islands of Indonesia. 256 are spoken on Papua; 17 on Java and Bali; 82 on Kalimantan (Borneo); 128 in Maluku; 63 in Nusa Tenggara; 114 on Sulawesi and 52 on Sumatra.

The national language is Bahasa Indonesian , spoken by 17-30 000 000 as a mother language and a further 140 000 000 as a second language. Javanese is widely spoken (75 200 000 speakers). The former colonial language of Dutch is still understood by some.

This is written Kepada yang terhormat.

Due to the great mixture of ethnic groups and languages found in Indonesia, the personal naming and form of address conventions of each group needs to be understood.

Many people in Indonesia have no family name, and if they use a second name it is the name of the father. Others use long names following Malay naming conventions or Muslim naming conventions. The Chinese community may use either localized names or transliterated Chinese names which follow the Chinese naming conventions. Some women take their husband’s name upon marriage, others do not.

Balinese use Hindu names, many a variant (affected by caste) indicating the birth order: Wayan/Yan (1st born) , Made (2nd born), Nyoman or Komang/Man/Mang (3rd born); and Ketut (4th born). A fifth child might become Wayan Balik ("Wayan again"). They do not use family names. A prefix I may be added as a prefix for females and Ni for males to indicate gender.

   Tables of names can be acquired: given names , surnames/family names , family name prefixes , forms of address , job titles
