Yook 육 — Korean last name
Is Yook a Korean last name?
Yes. Yook (Hangul: 육, Hanja: 陸) is a Korean family name recorded in the 2015 South Korean census with 23,455 holders, making it the #73 most common of the 191 surnames counted. Roughly one in every 2,119 South Koreans is a Yook. It is uncommon enough that many Koreans will know only a few people who carry it.
How to write Yook in Korean
In Hangul, Yook is written 육. Its Hanja (Chinese character) is 陸. Unlike many Korean surnames, Yook has a single Hanja form, so every Yook in Korea shares the same character.
What does Yook mean?
The character 陸 means land, continent. As with most Korean surnames, the meaning comes from the Chinese character rather than from the Korean sound, so it says something about how the name was first written down (often a place, a virtue, an object or a Chinese dynasty) rather than describing the family. Koreans rarely think about the literal meaning of a surname in daily life, but it matters for genealogy and for choosing given names that pair well with it.
How common is Yook?
Yook is uncommon Korean surname. Just above it in the rankings is Ok (25,107) and just below it is In (22,363). For comparison, Kim, the most common surname, has 10,689,967 holders. All figures come from Statistics Korea's 2015 Population and Housing Census, which only counts surnames held by five or more people.
Spellings and romanization
Yook is the spelling most Korean families use on passports and in English. The official Revised Romanization (used by the South Korean government since 2000) is Yuk, and the older McCune–Reischauer system gives Yuk. Other spellings you will see in real life include Yook, Youk, Yug, Yuck, Ryuk. The variety exists because Korean passport rules let each family choose its own romanization, so spellings drifted over generations of emigration; in Korean, every one of these is the same 육.
How to pronounce Yook
Yook (육) is pronounced roughly as the Revised Romanization "Yuk" reads, with even stress on each syllable — Korean does not stress one syllable over another the way English does. Vowels are pure and short: "eo" is the "u" in "sun", "eu" is a tight "oo" with unrounded lips, and "ae" rhymes with "day".
Is Yook Chinese or Korean?
Both, in a sense — the character is shared, the family is not. Korean surnames were written with Chinese characters for over a thousand years, so nearly every Korean surname has a Chinese (and Vietnamese) reading: 陸 is Lù in Mandarin and Lục in Vietnamese. A Korean Yook and a Chinese family with the same character are not related; they simply adopted the same character at different times and places. If someone spells their name "Yook" they are almost certainly Korean, because the Chinese and Vietnamese romanizations look different. See our full guide to Korean vs Chinese last names.
