Mesoamerica can be divided into smaller linguistic subareas wherein linguistic diffusion has been especially intense, or where certain families have extended to become predominant. One such subarea would be the Maya area, roughly covering the Yucatán Peninsula, Guatemala, Belize, Chiapas and Tabasco, where Mayan languages have been highly predominant. The eastern and western fringes of this area have also been home to Xincan (now extinct) and Zoquean speakers respectively, though Mayan languages have encroached upon their territory over time. The Pacific coast was also home to Tapachultec and, beginning in the postclassic period, Nawat, both of which are now extinct here.
