Indian language – and youths have learned their languages only when they came of age and started taking part in the adult society. Within the last 20 years there has been an overt change in the policies of governments of Mesoamerican countries towards the indigenous languages. There has been official recognition of their right to existence and some kind of governmental support, to the point of recognizing them as national languages. Bilingual (rather than monolingual Spanish) education has been recognized as desirable even if not always actually achieved in practice. In Guatemala the recognition of the indigenous languages as official languages and a valuable part of the country's identity came after the Civil War which ended in 1996. In Mexico shifting governments had talked about the value of the country's indigenous heritage but it was not until 2003 that the Ley General de Derechos Lingüísticos de los Pueblos Indígenas established a framework for the conservation, nurturing and development of indigenous languages. Despite these official changes, old attitudes persist in many spheres, and indigenous languages are not in any practical sense on a par with Spanish. At present the linguistic situation of Mesoamerican languages is most difficult in the Central American countries like Honduras, El Salvador and Nicaragua where indigenous languages still do not enjoy the rights or privileges now granted them elsewhere, and are still subject to social stigmatization. Map of current distribution Writing Mesoamerica is one of the relatively few places in the world where writing has developed independently throughout history. The Mesoamerican scripts deciphered to date are logosyllabic combining the use of logograms with a syllabary, and they are often called hieroglyphic scripts. Five or six different scripts have been documented in Mesoamerica but archaeological dating methods make it difficult to establish which was earliest and hence the forebear from which the others developed. Candidates for being the first writing system of the Americas are Zapotec writing, the Isthmian or Epi-Olmec script or the scripts of the Izapan culture. The best documented and deciphered Mesoamerican writing system, and hence the most widely known, is the classic Maya script. Post-Classic cultures such as the Aztec and Mixtec cultures do not seem to have developed true writing systems, but instead used semasiographic writing although they did use phonetic principles in their writing by the use of the rebus principle. Aztec name glyphs for example do combine logographic elements with phonetic
