How to write Deungjeong in Korean
In Hangul, Deungjeong is written 등정. Its Hanja (Chinese character) is 藤井. Unlike many Korean surnames, Deungjeong has a single Hanja form, so every Deungjeong in Korea shares the same character.
What does Deungjeong mean?
The character 藤井 means a surname of Japanese origin (Fujii). 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 Deungjeong?
Deungjeong is ultra-rare Korean surname. Just above it in the rankings is Wan (6) and just below it is Tang (5). 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
Deungjeong 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 Deungjeong, and the older McCune–Reischauer system gives Tŭngjŏng. 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 등정.
How to pronounce Deungjeong
Deungjeong (등정) is pronounced roughly as the Revised Romanization "Deungjeong" 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".
