チョンタル語はいつごろ誕生した
Yucatec Maya forms part of the Yucatecan branch of the Mayan language family. The Yucatecan branch divides into the subgroups Mopan-itza and Yucatec-Lacandon, which in turn split into four languages: Itza, Mopan, Yucatec Maya, and Lacandon. All the languages in the Mayan language family are thought to originate from an ancestral language that was spoken some 5,000 years ago, known as Proto-Mayan.
