Mesoamerican languages are the languages indigenous to the Mesoamerican cultural area, which covers southern Mexico, all of Guatemala and Belize and parts of Honduras and El Salvador. The area is characterized by extensive linguistic diversity containing several hundred different languages and seven major language families. Mesoamerica is also an area of high linguistic diffusion in that long-term interaction among speakers of different languages through several millennia has resulted in the convergence of certain linguistic traits across disparate language families. The Mesoamerican sprachbund is commonly referred to as the Mesoamerican Linguistic Area.
