Generally Indonesian does not make use of grammatical gender, and there are only selected words that use natural gender. For instance, the same word is used for he and she (dia/ia) or for his and her (dia/ia/-nya). No real distinction is made between "girlfriend" and "boyfriend", both pacar (although more colloquial terms as cewek girl/girlfriend and cowok guy/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 (a characteristic quite common to many Asian languages). For example, adik refers to a younger sibling of either gender and kakak refers to an older sibling, again, either male or female. In order to specify the natural gender of a noun, an adjective must be added. Thus, adik laki-laki corresponds to "younger brother" but really means "male younger sibling".
There are some words that are gendered, for instance putri means "daughter", and putra means "son" and also pramugara means "air steward" (male flight attendant) and pramugari meaning "air stewardess" (female flight attendant). Another example would be olahragawan, which equates to "sportsman", and olahragawati, 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 through the Old Javanese language). In some regions of Indonesia such as Sumatera and Jakarta, abang (a gender-specific term meaning "older brother") is commonly used as a form of address for older siblings/ males, whilst kakak (a non-gender specific term (meaning "older sibling") is often used to mean "older sister". Similarly, more direct influences from dialects such as Javanese and Chinese languages have also seen further use of other gendered words in Indonesian. For example: Mas (Jav. = older brother), M'bak (Jav. = older sister),Koko (older brother) and Cici (older sister).
