Mukomuko language

The Mukomuko language (bahaso Mukomuko) is a language in the Minangkabau language family spoken by the Mukomuko people, a subgroup of the Minangkabau people living in Mukomuko Regency in northern Bengkulu that borders West Sumatra. In 1993, there were an estimated 26,000 Mukomuko speakers. Mukomuko is closely related to the Minangkabau language and shares similarities with the Pancung Soal dialect, spoken in the southern part of Pesisir Selatan Regency in West Sumatra. The distribution area of this dialect also extends to the northern part of Mukomuko Regency. Geographically, Mukomuko is situated on the border between Bengkulu and West Sumatra, which fosters interaction between the people of Mukomuko and the Minangkabau. This proximity results in a culturally rich environment, representing the convergence of two or more cultures.

The native inhabitants of northern Mukomuko are the Minangkabau people. Traditionally, culturally, and linguistically, they are closely related to the Pesisir Selatan of West Sumatra. In the past, the Mukomuko region was part of the Pesisir Selatan diaspora of the Minangkabau. In addition to the Minangkabau, the southern part of Mukomuko regency is inhabited by the Pekal people. The Mukomuko region is also a Minangkabau diaspora (rantau) area, often referred to as the Riak nan Berdebur region, along the west coast from Padang to South Bengkulu. However, since the British colonial period, the Mukomuko region has been politically separated from West Sumatra. Since then, the Mukomuko people have been separated from their relatives in West Sumatra, which continued to the Dutch colonial period, the Japanese occupation, and into the independence era. Centuries of separation have resulted in the Mukomuko language gradually diverging from standard Minangkabau, particularly in its vocabulary. However, despite these changes, mutual intelligibility between the two dialects generally persists.

The Minangkabau language has been regarded as the lingua franca in northern Bengkulu, exerting its influence on neighboring languages like Bengkulu Malay, particularly in terms of phonology and vocabulary.

Mukomuko belongs to the Malayic languages branch of the Malayo-Polynesian subgroup of the Austronesian language family, which also includes Malay and standard Indonesian. Linguistically, it shares a strong resemblance with the Minangkabau language, particularly the Pesisir Selatan dialect spoken in the neighboring Pesisir Selatan Regency. Lexically, the Mukomuko language shares approximately 86% to 90% of its vocabulary with the Pesisir Selatan dialect. Due to these linguistic similarities, some research suggests classifying Mukomuko as a dialect of Minangkabau.

The majority of Mukomuko speakers lives in North Mukomuko District and South Mukomuko District of the Mukomuko Regency in northern Bengkulu. The capital of North Mukomuko District is Mukomuko, while the capital of South Mukomuko District is Ipuh. North Mukomuko District comprises 39 hamlets, and South Mukomuko District comprises 30 hamlets. In addition to Mukomuko, the community in these districts also speaks Javanese and Kerinci. Javanese is primarily spoken by transmigrants from Java, whereas Kerinci is spoken in the hamlets of Sungai Ipuh, Pondok Baru, and Sungai Jarinjing in North Mukomuko District. The geographical range of Mukomuko language speakers extends from Pondok Suguh hamlet in the south to Lubuk Pinang hamlet in the north.

Mukomuko generally only functions as a social language. It is used within family and community environments in daily life in informal settings. During wedding ceremonies, public meetings, mosque sermons, and other ceremonies, the Mukomuko people tend to code-switch between Indonesian and Mukomuko. Meanwhile, in government offices, schools, and formal settings, Indonesian is used. However, in the early grades of elementary school, teachers from the Mukomuko area often use the Mukomuko language to present the material. In markets and among the general public, the Mukomuko language is used among members of the Mukomuko community, while between people from different areas, a mix of Mukomuko and Indonesian or other regional languages is used.

As of 2024, recognizing the importance of preserving local languages, the regional government of Mukomuko has initiated the inclusion of regional languages such as Rejang, Mukomuko, and Serawai in the school curriculum.

Like other Malayic languages, there are five different vowels in Mukomuko, which are /i/, /e/, /a/, /u/, and /o/. The Mukomuko language mostly follows the standard Indonesian orthography. The table below illustrates the vowel chart of the Mukomuko language.
