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: • 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
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.
Pangaraian The Pangaraian dialect or the Rokan Hulu dialect is spoken in
Rokan Hulu Regency, located in western Riau near the borders of
North Sumatra and
West Sumatra. This region serves as a linguistic and cultural crossroads, which has led to substantial influence from neighboring languages, particularly
Minangkabau and
Mandailing. These influences are largely the result of long-standing migration patterns, intermarriage, and trade between communities across provincial boundaries. The geographical distribution of Pangaraian Malay speakers overlaps significantly with that of the
Mandailing people, an ethnic group originally from North Sumatra. As a result, frequent social interaction between the two groups has fostered widespread bilingualism. Many speakers of Pangaraian Malay are also proficient in the Mandailing language, and language mixing is commonly observed in informal communication. In addition to lexical borrowing, Pangaraian Malay also exhibits grammatical influence from Minangkabau. This includes the use of certain Minangkabau syntactic constructions, affixes, and pronouns that are not typically found in other Riau Malay dialects.
Pelalawan The Pelalawan dialect is spoken in
Pelalawan Regency. It is notably distinct from other Riau Malay dialects, particularly in terms of phonology. One prominent difference involves the vowels /o/ and /e/. In other Riau Malay dialects, the vowel /o/ often corresponds to /e/ in Pelalawan Malay. For instance, the word
pesan ‘order’ is pronounced /pesan/ in Pelalawan Malay, but /posan/ in other Riau Malay dialects. In several varieties of Riau Malay, especially in inland areas, there is a tendency to either omit aspiration on consonants or replace it with other sounds. For example, the consonant /p/ may be pronounced as /b/ or /f/. The word
pulang 'to go home', for instance, may be pronounced as /bulang/ or /fulang/. In contrast, Pelalawan Malay tends to maintain aspiration on consonants more consistently, with no significant phonetic deviations observed in the pronunciation of aspirated consonants. This dialect also formed the basis for
Pedoman Bahasa, a grammar book authored by the historian and linguist
Raja Ali Haji, which became a key reference for the Malay language. The standardized form of Malay derived from this tradition (known as
bahasa Melayu baku) was later proclaimed the national language, Bahasa Indonesia, at the Indonesian
Youth Pledge on 28 October 1928. Some Malay individuals are even able to speak Chinese dialects, a result of frequent interactions between the native Malay and Chinese communities.
Rokan Hilir The Rokan Hilir dialect is spoken in
Rokan Hilir Regency in northern Riau, just across the border from
North Sumatra. It is generally considered part of the
o variety of Riau Malay, as words that typically end in /a/ are pronounced as /o/. The dialect is regarded as a blend of the Riau Coastal and Rokan Hulu dialects, as it exhibits features from both.
Siak The Siak dialect is spoken in both
Siak Regency and the provincial capital of Riau,
Pekanbaru. As Pekanbaru functions as a cultural melting pot in Riau, the Siak dialect spoken there has absorbed features from both coastal and inland varieties of Riau Malay. In Pekanbaru, this variety is recognized as a unifying language (
bahasa persatuan) among its diverse communities. Siak Malay comprises two main dialects: the 'e' dialect and the 'o' dialect. The 'e' dialect is regarded as a form of
Classical Malay, exhibiting minimal differences from Classical or High Malay. It is considered the refined or formal variety of Siak Malay, historically spoken in and around the
Siak Sri Indrapura Palace. Examples of this dialect in interrogative words include
siape (who),
kemane (where to),
dimane (where), and
beghape (how much). In contrast, the 'o' dialect developed among the general population and serves as the vernacular for daily communication. Also known as
bahaso Melayu Kampong (village Malay), this variety emerged in the villages surrounding the former administrative center of
Siak Sri Indrapura. Today, the 'o' dialect is the most widely spoken form of Siak Malay. Following the relocation of Siak’s trading center to Pekanbaru, this dialect was carried by Siak merchants and became commonly used by communities along the
Siak River. An example of Banjar influence on Tembilahan Malay is the significant number of Banjar loanwords that have been absorbed into the local variety. One notable example is the use of kinship terms in everyday greetings. Terms such as
abah (father),
uwak laki (uncle), and
uwak bini (aunt) are borrowed from Banjar and commonly used in Tembilahan Malay. == Literature ==
