the language came in the 1600s with the introduction of compulsory Spanish language education in Colombia. The education system was designed to suppress Nasa Yuwe. The Colombian empire pushed assimilatory policies that forced citizenship upon indigenous people and forced schooling on them to 'civilize' them. Children who spoke in their native language were punished, in some cases by being forced to kneel on grains of corn for hours. Thus, people were forced to avoid their languages. Revitalization With the General Law of Education, ethnoeducation is the opportunity of education for ethnic groups, but education needs to be related to the culture, traditions, language, and native elements of ethnic groups. To achieve the goal to give importance to indigenous languages, it is important to ensure that future indigenous generations preserve and relearn languages that do not have social privilege in Colombian society. Thus, it was necessary to implement booklets and original content material in different languages.

The goal of the campaign is to reinforce the use of the language in the education environment and the family environment because they are children's first and most influential contacts. The last step is to promote the project to being used with other endangered languages of our country and revitalize them. it is also necessary to create a conscience in the rest of society to avoid the marginalization of the people who speak these native languages.
