Initial sound rule

The initial sound rule () is series of changes to Hangul, the writing system for the Korean language, made in South Korea to better reflect modern Korean phonology. The changes affect syllable-initial r and n sounds in Sino-Korean vocabulary under certain conditions. In North Korea, the orthography does not recognize this rule, which makes it one of a number of NorthÃ¢ÂÂSouth differences in the Korean language.

Background

In native Korean words, r does not occur at the beginning (onset) of syllables, unlike in Chinese loanwords. Literature from as early the 16th century shows that pronunciation of Sino-Korean words was nativized enough that the new sounds began to be reflected. In the 17th century, the original version of Hendrick Hamel's book also records placenames that reflect the rules of pronunciation, such as Naedjoo for Naju (Hanja: ) and Jeham for Yeongam (Hanja: ). In the late 19th and the early 20th centuries, there were also cases of the surname Lee being also romanized as "Ye," "Yi," etc.

Thus, the claim of Professor Emeritus Ryeo Jeoung-dong (Ã«Â Â¤Ã¬Â¦ÂÃ«ÂÂ) that the initial sound rule and the final consonant notation were first organized in the Korean orthography for elementary schools in 1912, during the Korean colonial period, is not true. He works for the Department of Korean Literature at Gyeongsang National University and is South Korea's representative proponent for the abolition of the initial sound rule.

In Modern Korean, the South Korean standard language recognizes the initial sound rule except in a few conditions. While the North Korean standard language briefly adhered to the initial sound rule, it soon abandoned it. North Korea no longer follows the rule today except in a few cases and instead uses the earlier spellings for Sino-Korean vocabulary.

Specific rules made by the National Institute of Korean Language

The National Institute of Korean Language made three rules regarding initial sounds:

When the Chinese consonants "nyeo, nyo, nyu, ni" appear at the beginning of a word, they are written as "yeo, yo, yu, i" according to the initial sound rule.
When the Chinese consonants "rya, ryeo, rye, ryo, ryu, ri" appear at the beginning of a word, they are written as "ya, yeo, ye, yo, yu, i" according to the initial sound rule.
When the Chinese consonants "ra, rae, ro, roe, ru, reu" appear at the beginning of a word, they are written as "na, nae, no, noe, nu, neu" according to the initial sound rule.
