The term "Malayic" was first coined by in his lexicostatistical classification of the Austronesian languages. Dyen's "Malayic hesion" had a wider scope than the Malayic subgroup in its currently accepted form, and also included Acehnese, Lampung and Madurese. narrowed down the range of Malayic, but included the non-Malayic languages Rejang and Embaloh:
Rejang
Embaloh
Salako
Iban-Malayan
*Iban
*Malayan
The present scope of the Malayic subgroup, which is now universally accepted by experts in the field, was first proposed by K.A. Adelaar, based on phonological, morphological and lexical evidence.
While there is general consensus about which languages can be classified as Malayic, the internal subgrouping of the Malayic languages is still disputed.
Adelaar (1993)
Adelaar classifies the Malayic languages as follows.
Iban
*
*Standard Malay
*Minangkabau
*Middle Malay
*Banjarese
*Jakartanese
*Others
Ross (2004)
Based on grammatical evidence, Ross divides the Malayic languages into two primary branches:
Following, Anderbeck makes a distinction between Malay and Malayic in his discussion about the dialects of the Sea Tribes in Riau Archipelago. He tentatively classifies all Malayic languages as belonging to a "Malay" subgroup, except Ibanic, Kendayan/Selako, Keninjal, Malayic Dayak and the "fairly divergent varieties" of Urak Lawoi' and Duano.
Ibanic
Kendayan/Selako
Keninjal
Malayic Dayak
Urak Lawoi'
Duano
Malay
Anderbeck's classification has been adopted in the 17th edition of the Ethnologue, with the sole exception of Duano, which is listed in the Ethnologue among the "Malay" languages.
Smith (2017)
In his dissertation on the languages of Borneo, Smith provides evidence for a subgroup comprising Malayic isolects in western Borneo and southern Sumatra, which he labels "West Bornean Malayic". However, he leaves other isolects unclassified.
West Bornean Malayic
*Kendayan-Salako
*Besemah
*Ibanic
**Iban
**Seberuang
**Mualang
**Keninjal
Other Malayic
*Standard Malay
*Jakarta Malay
*Ketapang Malay
*Banjarese Malay
*Kutai Malay
*Brunei Malay
Position within Austronesian
The inclusion of the Malayic languages within the Malayo-Polynesian subgroup is undisputed, and there is general consensus that the Chamic languages are closely related to Malayic. The wider affiliations of the Malayic languages are however controversial. There are two major proposals: Adelaar places Malayic within the Malayo-Sumbawan subgroup, which comprises the following languages:
The Malayo-Sumbawan hypothesis is mainly based on phonological evidence with a few shared lexical innovations, while the Greater North Borneo hypothesis is based on a large corpus of lexical evidence.
