In its language policy and planning (LPP), Colombia offers ethnoeducation for ethnic groups, with Spanish as a second language, and for the protection/revitalization of native languages. However, these LPP measures are insufficiently implemented. Meanwhile, with regard to foreign languages, LPP have specifically advocated a Spanish-English bilingualism emphasized since the early 2000s. What then favours English to the detriment of native languages? The objective of this research is to reveal what is hidden behind this LPP through a Critical Discourse Analysis of official documents. The elements brought to light show "unilingualism" and "unibilingualism" ideologies that discriminate against native languages, and value the linguistic imperialism of English.
