The Bunun language (Chinese: 布農語) is spoken by the Bunun people of Taiwan. It is one of the Formosan languages, a geographic group of Austronesian languages, and is subdivided in five dialects: Isbukun, Takbunuaz, Takivatan, Takibaka and Takituduh. Isbukun, the dominant dialect, is mainly spoken in the south of Taiwan. Takbunuaz and Takivatan are mainly spoken in the center of the country. Takibaka and Takituduh both are northern dialects. A sixth dialect, Takipulan, became extinct in the 1970s.

The Saaroa and Kanakanavu, two smaller minority groups who share their territory with an Isbukun Bunun group, have also adopted Bunun as their vernacular.


The name Bunun literally means "human" or "man".


Bunun is currently subdivided into five dialects: Isbukun, Takbunuaz, Takivatan, Takibaka and Takituduh. Li (1988) splits these dialects into three main branches — Northern, Central, and Isbukun (also classified as Southern Bunun).[2] Takipulan, a sixth dialect, became extinct in the 1970s. Isbukun, the prestige dialect, is also the most divergent dialect. The most conservative dialects are in the Northern branch.

Bunun was originally spoken in and around Sinyi Township (Xinyi) in Nantou County.[3] From the 17th century onwards, the Bunun people expanded towards the south and east, absorbing other ethnic groups such as the Saaroa, Kanakanavu, and Thao. Bunun is spoken in an area stretching from Ren-ai Township in Nantou in the north to Yan-ping Township in Taitung in the south. Isbukun is distributed throughout Nantou, Taitung, and Kaohsiung. Takbanuaz is spoken in Nantou and southern Hualien County. Takivatan is spoken in Nantou and central Hualien. Both Takituduh and Takibakha are spoken in Nantou.


Shibata (2020) has a reconstruction of Proto-Bunun.[4]

Bunun is a verb-initial language and has an Austronesian alignment system or focus system. This means that Bunun clauses do not have a nominative–accusative or absolutive–ergative alignment, but that arguments of a clause are ordered according to which participant in the event described by the verb is 'in focus'. In Bunun, four distinct roles can be in focus:

Which argument is in focus is indicated on the verb by a combination of prefixes and suffixes.[7]

Many other languages with a focus system have different marking for patients, instruments and beneficiaries,[citation needed] but this is not the case in Bunun. The focussed argument in a Bunun clause will normally always occur immediately after the verb (e.g. in an actor-focus clause, the agent will appear before any other participant) and is in the Isbukun dialect marked with a post-nominal marker a.[7]

Bunun has a very large class of auxiliary verbs. Concepts that are expressed by auxiliaries include:

In fact, Bunun auxiliaries express all sorts of concepts that in English would be expressed by adverbial phrases, with the exception of time and place, which are normally expressed[clarification needed] with adverbial phrases.

Bunun is morphologically agglutinative language and has a very elaborate set of derivational affixes (more than 200, which are mostly prefixes), most of which derive verbs from other word classes.[8] Some of these prefixes are special in that they do not only occur in the verb they derive, but are also foreshadowed on a preceding auxiliary. These are called lexical prefixes[9] or anticipatory prefixes[10] and only occur in Bunun and a small number of other Formosan languages.

Below are some Takivatan Bunun verbal prefixes from De Busser (2009).
