Where it’s spoken: Korean is the national language of both North and South Korea, where it is the first language for nearly all the population. Beyond the Korean peninsula, it is spoken by an ethnic minority community of 1.7 million in bordering China (Jilin Province) and to a far lesser extent in Russia and other former Soviet republics. After China, due to emigration the next largest Korean communities are in the United States (over 1 million) and Japan. Since the 1990s, the increasing popularity of Korean pop culture (K-pop music, movies and TV) has boosted interest in Korean language learning… but the effect on the number of actual speakers is questionable.
Language family: The prime member of the Koreanic family. Its only related language is Jeju, native to Jeju (or Cheju) Island off the Korean coast. Possible kinship to other language families, including Japanese, Mongol, and Turkic, has been a matter of linguistic debate. Though Chinese is unrelated, centuries of Chinese influence have resulted in extensive loans to the Korean vocabulary, including such varied words as ‘mountain’, ‘river’, ‘university’, ‘democracy’, and the numbers used to count higher than 10.
Writing and pronunciation tips: Korean uses its own unique alphabet, known as Hangeul (한글), which was created to better reflect the sounds and structure of the Korean language. It was established in 1443 by King Sejong the Great and used alongside the Chinese characters (called ‘Hanja’ in Korean) that were originally used to write the language. Hanja were dropped from common usage only in the 20th century.
In contrast with most other alphabets, Korean letters are clustered into one-syllable blocks rather than written in straight lines. Within a syllable, the letter with the longest horizontal or vertical line is the vowel; two easily recognized consonants look like a square (‘M’) and a circle (silent at the beginning of a syllable, ‘NG’ at the end.) Korean has been transcribed into the Latin alphabet in various ways: for example, South Korea’s capital has a two-syllable name (“suh-ool”), but its two official Romanized spellings are Seoul and Sŏul. Korean names have also been Romanized inconsistently: the second-most common Korean surname is usually written Lee, but alternatively spelled Yi, I, Li, Ri, Rhee, and even Ni.
