Riau Malay (Riau Malay: Bahase Melayu Riau or Bahaso Melayu Riau, Jawi: بهاس ملايو رياو) is a collection of Malayic languages primarily spoken by the Riau Malays in Riau and the Riau Islands in Indonesia. The language is not a single entity but rather a dialect continuum consisting of numerous dialects, some of which differ significantly from one another. Each of these dialects has its own subdialects or isolects, which also exhibit differences from one another. Due to the influx of migrants from other parts of Indonesia, some Riau Malay dialects have been influenced by other regional languages of Indonesia, such as Bugis, Banjarese and Minangkabau. The Riau Malay dialect spoken on Penyengat Island in Tanjung Pinang, once the seat of the Riau-Lingga Sultanate, was recognized by the Dutch during the colonial era and became the lingua franca across the Indonesian archipelago. The Dutch standardized form of the Penyengat Riau Malay, known as Netherland Indies Malay, eventually evolved into standard Indonesian, the national language of Indonesia. To this day, Riau Malay remains widely used as a lingua franca in Riau and the surrounding regions, alongside Indonesian. Most Riau Malays are bilingual, fluent in both Riau Malay and Indonesian.

Riau Malay is the most widely used regional language in Riau, both before and after the division of the Riau Islands. However, only 65% of the Malay population in Riau use it as their daily language. In addition, Riau Malay can be found in Malay literature, both written and oral. Traditional Malay literary works commonly found in Riau include pantun, syair, gurindam, and hikayat. The use of Riau Malay is under threat due to modernization and the growing influence of standard Indonesian, the official language of education. However, efforts are being made by both the government and local Riau Malay communities to preserve the language. These efforts include promoting the use of traditional oral literature. Additionally, the Jawi script, the traditional writing system of Riau Malay before the introduction of the Latin script during European colonization, is now being taught in schools across Riau as part of the local language curriculum.

Classification Riau Malay is a Malayic language. Speakers of Malayic languages are spread from Brunei, Indonesia, Malaysia, Singapore, Southern Thailand, to the southernmost part of the Philippines. Malay is a member of the Austronesian family of languages, which includes languages from Taiwan, Southeast Asia, and the Pacific Ocean, with a smaller number in continental Asia. Malagasy, a geographic outlier spoken in Madagascar in the Indian Ocean, is also a member of this language family. Although these languages are not necessarily mutually intelligible to any extent, their similarities are often quite apparent. In more conservative languages like Malay, many roots have come with relatively little change from their common ancestor, Proto-Austronesian. There are many cognates found in the languages' words for kinship, health, body parts and common animals. Numbers, especially, show remarkable similarities.

Riau Malay is closely related to neighboring languages such as Minangkabau and Jambi Malay. It shares a significant number of lexical items with Minangkabau. Some Riau Malay dialects, particularly those spoken in western Riau near the West Sumatra border, also exhibit strong Minangkabau influence. The Pangaraian dialect spoken in Rokan Hulu, for example, shows considerable influence from both Minangkabau and Mandailing. The status of the Kampar and Kuantan varieties is debated. These varieties are sometimes considered dialects of Riau Malay, and most of their speakers identify as Riau Malays. However, some linguists classify them as dialects of Minangkabau due to their significant lexical and phonological influence from Minangkabau. The two languages are also generally very similar and mutually intelligible with the Minangkabau spoken in West Sumatra. The Tembilahan dialect, spoken in Indragiri Hilir in southeastern Riau, on the other hand, shows significant influence from Banjarese due to the large population of Banjarese migrants from South Kalimantan in the region.

The variety of Malay spoken in the northernmost regencies of the Riau Islands, Anambas and Natuna, is very different from Riau Malay and not mutually intelligible with it. As a result, these varieties are generally not considered dialects of Riau Malay. The Anambas Malay dialect shares some similarities with Pontianak Malay, spoken in West Kalimantan, and Belitung Malay, spoken in the Bangka-Belitung Islands, particularly in terms of vocabulary and phonology. In contrast, the Malay dialect spoken in Natuna is strongly influenced by Terengganu Malay and Pahang Malay, which are spoken in the Malaysian states of Terengganu and Pahang along the eastern coast of Peninsular Malaysia. Similarly, the aboriginal Malay languages spoken in Riau and the Riau Islands, such as Akit, Bonai, Talang Mamak, and the Orang Laut languages, are also generally not considered dialects of Riau Malay, although they are related to it to some extent.

Geographic distribution and usage Riau Malay is spoken throughout Riau and the Riau Islands. It is also spoken in the southeastern parts of North Sumatra that border Riau, particularly in Labuhanbatu Regency. Riau Malay is primarily spoken by the Riau Malays but is also used by members of other ethnic groups who have migrated from different regions of Indonesia, such as the Javanese. It is common for these communities to engage in code-mixing or code-switching between Riau Malay, standard Indonesian, and their native languages. In Pekanbaru, for example, where Minangkabau is the dominant language due to a large influx of migrants from West Sumatra, many people often code-switch between Minangkabau and Riau Malay, particularly in informal settings such as markets. In more formal settings, such as educational and government institutions, Indonesian, the national language, is generally preferred, as it serves as the primary lingua franca for interethnic communication.

In Riau, Riau Malay holds a significant role in the cultural life of the local Malay community. As the historical center of several Malay kingdoms and sultanates, the region has a strong cultural heritage that continues to influence the preservation and use of Riau Malay. However, the use of the Riau Malay language is increasingly under threat due to the influx of migrants from other parts of Indonesia, such as Java, who bring their own native languages. These migration flows were largely driven by the transmigration program, an initiative that began during the Dutch colonial era and was continued by the Indonesian government to resettle populations in less densely populated areas like Riau. Significant efforts have been made to preserve the use of Riau Malay. For example, many schools in Riau now include Riau Malay in their curriculum, often focusing on learning to write in the traditional Jawi script. Additionally, several universities in Riau offer programs in Malay literature, further supporting the preservation and study of the language and its cultural heritage. Furthermore, the Riau Malay Cultural Councils (Indonesian: Lembaga Adat Melayu Riau) have now been established across various regions of Riau. These councils function as cultural advocates and play an active role in supporting the preservation of the Riau Malay language and cultural heritage.

Dialects Each region in Riau and the Riau Islands has its own distinct dialects, which may also include subdialects that vary from one another. For instance, one village in Riau may speak a dialect that differs from another village's dialect. The exact number of Riau Malay dialects is a topic of debate. Hamidy (2002) identified six distinct dialects of Riau Malay, which are primarily differentiated by variations in intonation and vocabulary:Hamidy, U. U. 2003, Bahasa Melayu dan Kreativitas Sastra di Riau / U.U. Hamidy Unri Press kerjasama dengan Yayasan Adikarya Ikapi dan The Ford Foundation Pekanbaru, ISBN 979-3297-33-6 Dialect of isolated communities Petalangan Rokan Rantau Kuantan Kampar Riau Coastal Riau Malay can generally be divided into two main groups: inland dialects and coastal dialects. The inland dialects exhibit phonological features similar to Minangkabau, while the coastal dialects are closer to the Malay spoken in regions like Selangor, Johor, and Kuala Lumpur in Peninsular Malaysia. In addition to other distinguishing characteristics, the two groups differ in the pronunciation of words ending with the vowel /a/ in Indonesian. In the inland dialects, these words are pronounced with the vowel /o/, whereas in the coastal dialects, they are pronounced with the weak vowel /ə/. For example, the Indonesian words /bila/, /tiga/, and /kata/ (meaning "if," "three," and "word" in English, respectively) are pronounced as /bilo/, /tigo/, and /kato/ in the inland dialects, while in the coastal dialects, they are pronounced as /bilə/, /tigə/, and /katə/.

The most studied dialects of Riau Malay include the Indragiri Hulu dialect, Pangaraian dialect, Pelalawan, Riau Coastal dialect, Rokan Hilir dialect, Siak dialect, and Tembilahan dialect. The Kampar and Kuantan languages are often regarded as dialects of Riau Malay, although they are sometimes classified as dialects of Minangkabau due to their closer similarities to it than to other Malay dialects.

Indragiri Hulu The Indragiri Hulu dialect is primarily spoken in Indragiri Hulu Regency. It shares many features with the Riau Coastal dialect. Additionally, some varieties of the Indragiri Hulu dialect exhibit influence from the Kuantan language, particularly in areas bordering Kuantan Singingi Regency.

Kampar and Kuantan

The Kampar and Kuantan languages are primarily spoken in Kampar Regency and Kuantan Singingi Regency in southwestern Riau, near the border with West Sumatra. Their linguistic classification remains a topic of debate, as they are variously regarded as dialects of either Riau Malay or Minangkabau. Both languages exhibit significant lexical and grammatical influence from Minangkabau and are generally mutually intelligible with some Minangkabau dialects. While the Minangkabau community often considers them part of the broader Minangkabau linguistic family, speakers of Kampar and Kuantan typically identify as Riau Malays and refer to their speech as dialects of Riau Malay. The Indonesian government’s classification of the Kuantan language is also inconsistent, sometimes categorizing it as a dialect of Minangkabau and at other times as part of Riau Malay. Geographically located between the Minangkabau-speaking region to the west and the Riau Malay-speaking region to the east, the Kampar and Kuantan languages have been shaped by mutual linguistic influence, forming part of a dialect continuum in central Sumatra.Witrianto and Arfinal (2011).
