Neoliberalism regards language is a pure potentiality medium, which can accomplish any communicative speaker aim, thus a key for opening individual covert potential. A global language like English likely enables speakers to surpass culture and community restrictions, getting to many people and crossing multiple markets, no longer choked by the borders inlicted by essentialized identity. By blurring language's social context embeddedness, this ideology renders the language learner as a liable neoliberal subject investing in eternal self-development. To exemplify this process, this paper sketches how the ideology of language as pure potential adds to the leading position of English in South Korea's neoliberal mutation.
