Mayan languages system developed by the Academia de Lenguas Mayas de Guatemala (ALMG). Orthographies for the languages of Mexico are currently being developed by the Instituto Nacional de Lenguas Indígenas (INALI). The pre-Columbian Maya civilization developed and used an intricate and fully functional writing system, which is the only Mesoamerican script that can be said to be almost fully deciphered.
