|Linguistic classification:||proposed language family|
Sino-Austronesian is a proposed language family. Its original version was first presented by Laurent Sagart in the early 1990s. Using reconstructions of the Old Chinese language, Sagart argued that the Austronesian languages were related to the Sinitic languages both lexically and morphologically. Additionally, the Tai–Kadai languages were placed internally within the Austronesian family as a sister branch of Malayo-Polynesian. He also considers the Austroasiatic language family to be a likely candidate for inclusion, since if the Austric hypothesis proves to be true, Austroasiatic would follow along with the Tai–Kadai branch's inclusion in Sino-Austronesian.
If compared with genetic evidence, the Sino-Austronesian family would correspond to Haplogroup O, a paternally-transmitted human Y-chromosome DNA haplogroup. Laurent Sagart has also shown that his Sino-Austronesian proposal does not contradict genetic studies in any major way.
French linguist and Sinologist Laurent Sagart groups the Austronesian languages in a recursive-like fashion. Sagart considers the Austronesian languages to be related to the Sino-Tibetan languages, and also groups the Tai–Kadai languages as more closely related to the Malayo-Polynesian languages. As a result, Sagart rejects the Austro-Tai hypothesis in its original form, instead considering the Tai–Kadai languages to be fully within the Austronesian branch.
- Sino-Austronesian (Sino-Tibetan–Austronesian)
Ostapirat (2005) supports the link between Austronesian and Kra–Dai (Sagart built upon Ostapirat's findings), but rejects a link to Sino-Tibetan. He notes that the apparent cognates are rarely found in all branches of Kra–Dai, and almost none are in core vocabulary.
