Jeju language is more unique than other dialects in other regions. It retains a lot of medieval Korean vocabulary, such as down-a (ㆍ) and double down-a (ㆍㆍ), which have disappeared from modern Korean. However, the linguistically valuable Jeju language is currently under threat of extinction. UNESCO designated Jeju as a "critically endangered" language, level 4 out of 5. Standardized education has led to a significant decline in the use of Jeju language among young people, accelerating the dying out crisis. There is an urgent need for a movement to preserve the language among young people, especially students, as they are the ones who can play the biggest role in preserving the language.

Jeju National University is making an effort by organizing an annual 'Jeju language speaking contest' for students in the province. The Jeju Provincial Office is also planning to apply to the UNESCO Intangible Cultural Heritage for the Jeju language designation.

However, this is not enough to attract the attention of young people. It is necessary to promote the Jeju language through media. In 2020, a meme based on an old woman's interview in Jeju language during a typhoon's landfall was a big hit. The meme sparked a surge of interest in the Jeju language. Properly utilizing media like this can help attract more attention. In addition to this, Jeju language education programs should be developed in schools so that students can experience the language firsthand.

Jeju is not just a regional language, but a valuable resource that best represents the essence of our national language. It is time for everyone to be aware of the threat of the language's disappearance and participate in its preservation.
