"boyfriend", both (although more colloquial terms as girl/girlfriend and boy/boyfriend can also be found). A majority of Indonesian words that refer to people generally have a form that does not distinguish between the sexes. However, unlike English, distinction is made between older or younger. There are some words that have gender: for instance, means "daughter" while means "son"; means "male flight attendant" while means "female flight attendant". Another example is , which means "sportsman", versus , meaning "sportswoman". Often, words like these (or certain suffixes such as "-a" and "-i" or "-wan" and "wati") are absorbed from other languages (in these cases, from Sanskrit). In some regions of Indonesia such as Sumatra and Jakarta, (a gender-specific term meaning "older brother") is commonly used as a form of address for older siblings/males, while (a non-gender specific term meaning "older sibling") is often used to mean "older sister". Similarly, more direct influences from other languages, such as Javanese and Chinese, have also seen further use of other gendered words in Indonesian. For example: ("older brother"), ("older sister"), ("older brother") and ("older sister"). Number Indonesian grammar does not regularly mark plurals. In Indonesian, to change a singular into a plural one either repeats the word or adds para before it (the latter for living things only); for example, "students" can be either or . Plurals are rarely used in Indonesian, especially in informal parlance. Reduplication is often mentioned as the formal way to express the plural form of nouns in Indonesian; however, in informal daily discourse, speakers of Indonesian usually use other methods to indicate the concept of something being "more than one". Reduplication may also indicate the conditions of variety and diversity as well, and not simply plurality. Reduplication is commonly used to emphasise plurality; however, reduplication has many other functions. For example, orang-orang means "(all the) people", but orang-orangan means "scarecrow". Similarly, while hati means "heart" or "liver", hati-hati is a verb meaning "to be careful". Also, not all reduplicated words are inherently plural, such as orang-orangan "scarecrow/scarecrows", biri-biri "a/some sheep" and kupu-kupu "butterfly/butterflies". Some reduplication is rhyming rather than exact, as in sayur-mayur "(all sorts of) vegetables". Distributive affixes derive mass nouns that are effectively plural: pohon "tree", pepohonan "flora, trees"; rumah "house", perumahan "housing, houses"; gunung "mountain", pegunungan "mountain range, mountains". Quantity words come before the noun: seribu orang "a thousand people", beberapa pegunungan "a series of mountain ranges",
