Pronouns - As indicated above, a strong sense of social hierarchy attaches to the personal pronouns for "I" and "you". For this reason, Indonesians prefer to use first names or the polite forms of address given in the previous post rather than these personal pronouns. In conversation with someone you are meeting for the first time or meeting on a formal basis, it is more polite to refer to them as bapak or ibu followed by the person's first name (if known) rather than using the pronouns for "you".
1st person singular : saya, aku
1st person plural : kita, kami
2nd person singular : anda, saudara, kamu, engkau, bapak, ibu
2nd person plural : kalian, saudara sekalian, anda sekalian
3rd person singular : dia
3rd person plural : mereka
Note : Indonesian pronouns do not distinguish gender, thus dia may mean he, she or it.
1st person (singular): saya, aku
Use your own name with people who know you, or else the pronoun saya (which originally meant "your slave" but know generally means "I"). Aku also means "I" but used in more informal circumstances, as are the Jakarta slang forms gua and gue (which derive from Hokkien Chinese). Note that when requesting something, words for "I" are often omitted because this is understood.
1st person (plural): kita, kami
Kami means "we" or "us" but formally excludes the person or persons being addressed, whereas kita includes the person or persons you are speaking to. In everyday speech, kita is in both contexts and you may generally use this form to translate English "we".
2nd person (singular): anda, saudara, kamu, engkau, bapak, ibu
Use bapak or ibu. In informal circumstances, the first name alone may also be used. If the person the person being addressed is about the same age as yourself, use anda or saudara. Kamu or engkau may be used for children or you know the person well.
2nd person (plural): kalian, saudara sekalian, anda sekalian
3rd person (singular): dia, beliau
For animate objects and persons use dia. The word beliau[i/] is also used in formal circumstances to refer to a person of very high status who is not present. For inanimate things, use ini (this one) or itu (that one), to mean "it".
3rd person (plural): they mereka
