There are three common forms of "you", Anda (polite), kamu (familiar), and kalian "all" (commonly used as a plural form of you, slightly informal). Anda is used with strangers, recent acquaintances, in advertisements, in business, and when you wish to show distance, while kamu is used in situations where the speaker would use aku for "I". Anda sekalian is polite plural. Particularly in conversation, respectful titles like Bapak/Pak "father" (used for any older male), Ibu/Bu "mother" (any older woman), and tuan "sir" are often used instead of pronouns. Engkau (əngkau), commonly shortened to kau. Third person pronouns The common word for "s/he" and "they" is ia, which has the object and emphatic/focused form dia. Bəliau "his/her Honour" is respectful. As with "you", names and kin terms are extremely common. Mereka "someone", mereka itu, or orang itu "those people" are used for "they". Regional varieties There are a large number of other words for "I" and "you", many regional, dialectical, or borrowed from local languages. Saudara "you" (male) and saudari (female) (plural saudara-saudara or saudari-saudari) show utmost respect. Daku "I" and dikau "you" are poetic or romantic. Indonesian gua "I" (from Hokkien ) and lu "you" () are slang and extremely informal. The pronouns aku, kamu, engkau, ia, kami, and kita are indigenous to Indonesian. Possessive pronouns Aku, kamu, engkau, and ia have short possessive enclitic forms. All others retain their full forms like other nouns, as does emphatic dia: meja saya, meja kita, meja anda, meja dia "my table, our table, your table, his/her table". There are also proclitic forms of aku, ku- and kau-. These are used when there is no emphasis on the pronoun: Ku-dengar raja itu menderita penyakit kulit. Aku mengetahui ilmu kedokteran. Aku-lah yang akan mengobati dia. "It has come to my attention that the King has a skin disease. I am skilled in medicine. I will cure him." Here ku-verb is used for a general report, aku verb is used for a factual statement, and emphatic aku-lah meng-verb (≈ "I am the one who...") for focus on the pronoun. Demonstrative pronouns There are two demonstrative pronouns in Indonesian. Ini "this, these" is used for a noun which is generally near to the speaker. Itu "that, those" is used for a noun which is generally far from the speaker. Either may sometimes be equivalent to English "the". There is no difference between singular and plural. However,
