The national language policy consists of orthography standard supervision, purification of public and media language, the national language ability improvement, and the Korean language education. In the era of multiculture and internationalization, the national language policy of Korea needs to extend its vision toward language policy. The national language policy should abandon the prescriptivism of modern linguistics of which a nation controls language policies and be open by a liberal circulation of language and reduced national interference. The Korean language policy needs tolerant, universal, cultural, and educational openness to become an advanced first-rate nation. In the crises of low birth rate, the environmental degeneration and the degradedness of the national language, and aggravated miscommunication, openness of a population policy, vitalization of culture of discussion with attentive listening and questions to promote the national language ability, and deauthoritative openness should be the basis of language policy based on the native language identity. As individual communicative ability is the most important in language policy, communicative ability should be developed at home and schools based on individual communicative ability. Language policies for the transmission of overseas Koreans native language and multicultural families should be reinforced. For longitudinal communication, the ability to communicate with history should be reinforced, and policies for the Korean language education that helps eradicate illiteracy of Chinese characters and for promoting modernization of classics should be established.
