Sirayaic languages is one of the sub-branches of the Formosan branch, under the Austronesian languages family. Both Blust (1999) and Li (2010) considers Proto-Siraya belongs to East Formosan languages, along with Kavalanic and Amis languages.
The Proto-Siraya language is the reconstructed ancestor of the Siraiyac branch. Proto-Siraya includes at least three languages: Siraya, Taivoan, and Makatao. Li claimed Proto-Siraya might have split from the other East Formosan languages around 3,500 years ago, and began to develop nowadays Siraya, Taivoan, and Makatao 3,000 years ago.
