CEN (Nahuatl Encyclopedic Compendium) is a set of four programs that manage evolutionary contents of the Nahuatl language in three languages: Spanish, French and English.
CHACHALACA, "talking a lot", provides all the theoretically possible morphological analyzes of a word.
GDN, acronym for "Great Nahuatl Dictionary", is a collective and evolutionary work that brings together dictionaries prepared by authors from the sixteenth century to the present day. For Nahuatl, the original and standard spelling is presented, and for Spanish, the modernized spelling.
TEMOA, "search", is a text editor equipped with advanced functions to search for character strings. It is capable of generating all the theoretically possible spellings of Nahuatl. Searches are carried out on corpus: an evolutionary set of texts in Latin characters.
TLACHIA, "observe", presents in the form of pictographic dictionaries the content of an evolutionary set of codices, which have been studied especially for this purpose.
CEN, "together", is a way to words, written pictographically or alphabetically, which are one of the main keys to getting to know the men who used them and the societies in which they lived.
In the case of Nahuatl, it is essential to know the composition of the words, CHACHALACA, the virtual meanings that appear in the dictionaries, GDN, and the real meanings revealed in their employment contexts, TEMOA and TLACHIA.
