beberapa kupu-kupu "some butterflies". Plural in Indonesian serves just to explicitly mention the number of objects in sentence. For example, Ani membeli satu kilo mangga (Ani buys one kilogram of mangoes). In this case, "mangoes", which is plural, is not said as mangga-mangga because the plurality is implicit: the amount a kilogram means more than one mango. So, as it is logically, one does not change the singular into the plural form, because it is not necessary and considered a pleonasm (in Indonesian often called pemborosan kata). Pronouns Personal pronouns are not a separate part of speech, but a subset of nouns. They are frequently omitted, and there are numerous ways to say "you". Commonly the person's name, title, title with name, or occupation is used ("does Johnny want to go?", "would Madam like to go?"); kin terms, including fictive kinship, are extremely common. However, there are also dedicated personal pronouns, as well as the demonstrative pronouns ini "this, the" and itu "that, the". Personal pronouns From the perspective of a European language, Indonesian boasts a wide range of different pronouns, especially to refer to the addressee (the so-called second person pronouns). These are used to differentiate several parameters of the person they are referred to, such as the social rank and the relationship between the addressee and the speaker. Indonesian also exhibits pronoun avoidance, often preferring kinship terms and titles over pronouns, particularly for respectful forms of address. The table below provides an overview of the most commonly and widely used pronouns in the Indonesian language: First person pronouns Notable among the personal-pronoun system is a distinction between two forms of "we": kita (you and me, you and us) and kami (us, but not you). The distinction is not always followed in colloquial Indonesian. Saya and aku are the two major forms of "I". Saya is the more formal form, whereas aku is used with family, friends, and between lovers. Sahaya is an old or literary form of saya. Sa(ha)ya may also be used for "we", but in such cases it is usually used with sekalian or semua "all"; this form is ambiguous as to whether it corresponds with inclusive kami or exclusive kita. Less common are hamba "slave", hamba tuan, hamba datuk (all extremely humble), beta (a royal addressing oneselves), patik (a commoner addressing a royal), kami (royal or editorial "we"), kita, təman, and kawan.
