제주어 Jejueo for English speakers

1. Flashcards

2. What is Jejueo?

Jejueo (제주어, also Jejumal) is the language of Jeju Island, off the south coast of South Korea. It is part of the Koreanic family but differs so much from mainland Korean that the two are not mutually intelligible. Often called a "dialect," it is treated as a distinct language by scholars and by UNESCO, which classifies it as critically endangered (2010).¹

Jejueo preserves features that Standard Korean lost — most famously the vowel arae-a (ㆍ), which disappeared from the mainland in the 18th century. It also keeps Old Korean vocabulary and has a sentence-ending system entirely its own, plus loanwords from Japanese, Mongolian, and Manchu.

Why learn Jejueo?

• A living piece of Old Korean — The vowel arae-a (ㆍ) and archaic words survive here, gone from the mainland.
• Same roots, different language — Even for Korean speakers it's full of unfamiliar words and endings — a real second language.
• The heart of Jeju culture — The haenyeo divers, the dol hareubang statues, and the memory of 4·3 all live in this speech.
• Saving an endangered language — Learning and using it helps a preservation effort.

4. Essential Grammar

Jejueo's word order and particles are close to Korean (Subject–Object–Verb, with case particles), but the sentence endings differ sharply and the honorific system is simpler than Standard Korean's.

Distinctive sentence endings

Numbers and old words

Native numerals roughly parallel Korean native numbers (ᄒᆞ나, 둘, 싯, 넷, 다숫…). Jejueo also keeps Old Korean words such as 어시 (eosi) "parents."

Note the word 삼춘 (samchun): on Jeju it addresses any neighborhood elder, not only a blood uncle/aunt.

5. Pronunciation — arae-a (ㆍ)

The signature feature is the vowel arae-a (ㆍ), lost from Standard Korean in the 1700s but alive in Jejueo.

Jejueo is written in Hangul, using old letters such as arae-a (ㆍ) alongside the modern ones.

6. Common Mistakes

• Assuming it's "just a Korean accent" — the vocabulary and endings differ enough that you should approach it as a separate language.
• Reading ㆍ as plain ㅏ — arae-a is its own vowel, between ㅏ and ㅗ.
• Swapping in Standard Korean endings — endings like -수다 / -우꽈 are the core of what makes speech sound Jeju.
• Guessing vocabulary — many basic words are completely different: 아방 (father), 어멍 (mother), 도새기 (pig).
• Misreading 삼춘 (samchun) — it addresses neighborhood elders generally, not only relatives.

7. Learning Resources

• Jeju Talking Dictionary (Swarthmore) all levels — A Jejueo dictionary with audio; the best resource for checking pronunciation.
• Jeju Province official 《제주어 사전》 (Jejueo Dictionary) all levels — The provincial standard vocabulary reference.
• Jejueo Preservation Society materials beginner — Textbooks, events, and broadcasts from the preservation movement.
• Wikipedia & UNESCO endangered-language pages intermediate — Overview of the phonology, grammar, and preservation status.
• Elders and village gatherings on Jeju all levels — The living intonation and vocabulary are best heard in person.

8. Culture & Context

Samda-do and the haenyeo

Jeju is called Samda-do, "the island of three abundances": wind, stone, and women. Its haenyeo (women free-divers) are a UNESCO Intangible Cultural Heritage, and their language is Jejueo.

Dol hareubang and olle

The dol hareubang ("stone grandfather" guardian statues) and the olle (the narrow lane leading to a house) are Jeju icons — and Jejueo words.

"Poksak sogassuda"

The Jejueo phrase 폭삭 속았수다 ("thank you for your hard work") has recently become widely known through popular culture. A warm greeting goes a long way on Jeju.
