Abstract : This essay exposes some considerations related to the hidden curriculum, the teaching of the English language, and interculturality. The main objective is to explore how English has gained ground as a second language in relation to the concept of linguistic imperialism but also how the ideas about the predominance and relevance of learning English are transmitted through the hidden curriculum. The exposition of the ideas is based on the connection of some concepts and categories from the scholars of the hidden curriculum such as Henry Giroux and Michael Apple, as well as ideas on the linguistic imperialism of English by Robert Phillipson. Keywords : hidden curriculum, interculturality, linguistic imperialism, second language.
