The Austric macrofamily was first proposed by the German missionary Wilhelm Schmidt in 1906. He showed phonological, morphological, and lexical evidence to support the existence of an Austric phylum consisting of Austroasiatic and Austronesian.[4][a] Schmidt's proposal had a mixed reception among scholars of Southeast Asian languages, and received only little scholarly attention in the following decades.[5]
Research interest into Austric resurged in the late 20th century,[6] culminating in a series of articles by La Vaughn H. Hayes, who presented a corpus of Proto-Austric vocabulary together with a reconstruction of Proto-Austric phonology,[7] and by Lawrence Reid, focussing on morphological evidence.[8]
Among the morphological evidence, he compares reconstructed affixes such as the following, and notes that shared infixes are less likely to be borrowed (for a further discussion of infixes in Southeast Asian languages, see also Barlow 2022[10]).[11]
The first extension to Austric was first proposed Wilhelm Schmidt himself, who speculated about including Japanese within Austric, mainly because of assumed similarities between Japanese and the Austronesian languages.[14] While the proposal about a link between Austronesian and Japanese still enjoys some following as a separate hypothesis, the inclusion of Japanese was not adopted by later proponents of Austric.
Sergei Starostin adopted Benedict's extended 1942 version of Austric (i.e. including Kra–Dai and Hmong–Mien) within the framework of his larger Dené–Daic proposal, with Austric as a coordinate branch to Dené–Caucasian, as shown in the tree below.[17]
In the second half of the last century, Paul K. Benedict raised a vocal critique of the Austric proposal, eventually calling it an 'extinct' proto-language.[19][16]
Hayes' lexical comparisons, which were presented as supporting evidence for Austric between 1992 and 2001, were criticized for the greater part as methodologically unsound by several reviewers.[20][21]Robert Blust, a leading scholar in the field of Austronesian comparative linguistics, pointed out "the radical disjunction of morphological and lexical evidence" which characterizes the Austric proposal; while he accepts the morphological correspondences between Austronesian and Austroasiatic as possible evidence for a remote genetic relationship, he considers the lexical evidence unconvincing.[22]
A 2015 analysis using the Automated Similarity Judgment Program (ASJP) did not support the Austric hypothesis. In this analysis, the supposed "core" components of Austric were assigned to two separate, unrelated clades: Austro-Tai and Austroasiatic-Japonic.[23] Note however that ASJP is not widely accepted among historical linguists as an adequate method to establish or evaluate relationships between language families.[24]
^The terms "Austroasiatic" and "Austronesian" were in fact both coined by Schmidt. The previous common designations "Mon-Khmer" and "Malayo-Polynesian" are still in use, but each with a scope that is more limited than "Austroasiatic" and "Austronesian".
