Indonesian name

Indonesian names and naming customs reflect the multicultural and polyglot nature of over 17,000 islands in the Indonesian archipelago. The world's fourth most populous nation, Indonesia is home to approximately 365 tribal-ethnic groups, each with their own culture, customs, and language. The Javanese are the largest single group (40%). Over three hundred of these ethnic groups are officially recognized in the country.

In addition to the usual ranks and professional titles, it is customary to add Pak or Bapak and Saudara for addressing men, and Bu or Ibu for addressing women. Pak and Bapak are literally translated as "father", with Bapak being the more formal and used in speech much like the English word "sir". Saudara (for male) or Saudari (for female) is a term of greater respect and formality, literally translated as "kinsman", "ladies and/or gentlemen". Ibu is literally translated as "mother" and is used in speech much like the English words "ma'am" and "lady". For calling aperson whose name is not known an Indonesian man can be called as Bapak and an Indonesian woman as Ibu. Another informal way to address significantly older people is to call them Om/Paman and Tante, which mean "uncle" and "aunt". The terms are Dutch-influenced and quite commonly used in big cities.

However, local honorifics continue to be employed throughout Indonesia. As in the casual general sense Kakak is used for calling someone as older sister/brother; in Javanese Mbak is used for older sister. Mas is used for older brother; in Sumatran Malay or Minangkabau cultural spheres it corresponds to Abang for older brother, but it is common to call a becak driver, angkot driver, vegetable vendor, fishmonger or hawker abang. Additionally, 'Gus' (from bagus) is usually used exclusively to address honorable Eastern Javanese people with strong traditional and religious links. For example, Indonesian former president Abdurrahman Wahid is often addressed as 'Gus Dur'.

Indonesians do not generally use the Western naming practice of a given first name and a family last name. The majority of Indonesians do not have family names as westerners would understand them, but their given names are geographically and culturally specific. For instance, names beginning with "Su" in Indonesian spelling ("Soe" in Dutch orthography), or ending with an "o" are usually Javanese, for example Suprapto/Soeprapto, Joko. Balinese names are quite distinct, as they have a naming system which denotes birth order (Wayan: first born, Made: second born, etc.) and caste (I Gusti for Kshatriya, etc.), as well as gender beside personal names. Sitompul and Rajagukguk are clan names usually found in people with Batak or North Sumatran heritage. In general, Indonesian names fall into one of the following categories:
