What is the Kadazandusun language

The Kadazandusun language is a language that is spoken in the state of Sabah in the north of Borneo in Malaysia, mostly by the indigenous race over there in which the people of the race are called the Kadazans and the Dusuns (Simon). It is a member of the North Bornean branch of the Malayo-Polynesian language family, also one of the Austronesian language family. Kadazandusun refers to the form of language standardised by the Kadazandusun Cultural Association of Sabah, which is based on the Bundu-liwan dialect spoken in Bundu and Liwan, Sabah. The alphabets used in the language and its tone is pretty much similar to English alphabets.

A brief beginnings of the Kadazandusun

According to my online research (Herman, 2006), it is unclear from where the language originated. There is a legend, and one is that the Kadazan language, and maybe the Kadazan people, has its roots in the migration from the Southern China. Ancient Sabahans spoke their languages and dialects without much bothering as to their origins. Life in the valleys of north Borneo are mostly centered about the rice plantations and the village communities. Kadazans mainly inhabited flat valleys and deltas, an area where most are paddy field farms, however, the Dusuns traditionally inhabited the hilly regions where they cultivated ‘hill rice’.

The first Kadazandusuns to receive some form of school were the Papar, Kuala Penyu and the Penampang Kadazans. In early 1880’s, education was interrupted during the wars but resumed until the formation of Malaysia in 1963. Their schools were known as the ‘Native Voluntary Schools’ and appealed to the local Kadazan and Dusun because they opted to teach the rural folks initially through their local Kadazan or Dusun language before gradually shifting to English in the third and fourth year (Reid ,1997).

During the post-war years, the Kadazandusun language underwent some acceptance in the mass media usage; In 1953, Sabah’s first English newspaper ‘The Sabah Times’ had introduced a Kadazandusun section, and this remains the largest Kadazandusun newspaper section to this day. Since 1955, Radio Sabah followed suite, together with some other local publications. For more than half a century the language improved and developed more over the years due to its popularity.

After North Borneo (Sabah) joined Malaya in 1963 to form Malaysia, the mother-tongue language went into a great decline. Emphasis was now on the national language, Bahasa Malayu, which is a language of the Malays. For the sake of social and economic development as well as the integration into the fast-growing Malaysian culture, Kadazandusun parents had begun to allow the use of the Malay language in the home, hence not using the mother tongue language in the home.

In the early 1980’s, there were many 'broken' Kadazan and Dusun songs that broke into the music industry but had added further damage to the situation. Their fun and catchy tunes influenced the generation back then against original mother-tongue used by many Kadazandusun speakers themselves.

What has been done to conserve the language and its problems

There some schools that still teaches in the language itself, but only few; mainly in the rural areas of Sabah (Herman, 2006). There are even books on the language that are being sold today but those books are just phrasebooks four tourist and are in limited supply. On the contrary, even though there are some communities that still produce native speakers; they continue to speak their native tongue at home, even amongst siblings, and in their community. But only few make are able to speak the language.when they come into contact with other Kadazandusun, For instance, in a wet market, the sellers there are mostly the older generations of kadazandusun, hard for the youngsters to communicate to due to the language barrier; and it is not always because their languages and dialects differ as in most areas the Kadazandusun themselves like to view their language as underappreciated. For them, parents are emphasizing the Malay language more than their mother tongue on their children just so that they could have better chances in life when it comes to being socially contact with any Malay speakers out there.
