The 'Wastek' or 'Huastec' language is a
Mayan language of Mexico, spoken by the
Huastecs living in rural areas of
San Luis Potosí and northern
Veracruz. Though relatively isolated from them, it is related to the Mayan languages spoken further south and east in Mexico and Central America. According to the 2005 population census, there were about 150,000 speakers of Wastek in Mexico (some 90,000 in San Luis Potosi and some 50,000 in Veracruz)
[1].
The language is called 'Teenek' (with varying spellings) by its speakers, and this name has gained currency in Mexican national and international usage in recent years.
The now-exinct
Chicomuceltec language is believed to have been most closely related to Wastek.
The first description of the Huastec language accessible to Europeans was an "Arte" and Vocabulary written by
Andrés de Olmos, who also wrote the first such descriptions of
Nahuatl and
Totonac.
