Historical Korean Phonology: A Guide to the Sounds of Old Korean140

Historical Korean phonology is the study of the sound system of the Korean language at various points in its history. The Korean language has undergone significant sound changes over the centuries, and these changes have been documented in detail by linguists. The historical phonology of Korean is important for understanding the development of the modern language and for reconstructing the Proto-Korean language, the ancestor of all Koreanic languages.

The Middle Korean Period (10th-16th centuries)

The Middle Korean period is the earliest period for which we have extensive written records of the Korean language. The phonological system of Middle Korean was very different from that of modern Korean. The most striking difference was the presence of a series of voiced consonants, which have since been lost in modern Korean. Other notable differences include the presence of a three-way distinction between high, mid, and low vowels, and the absence of the modern diphthongs /ae/ and /oe/.

The following table shows the consonant inventory of Middle Korean:| | Labial | Dental/Alveolar | Palatal | Velar | Glottal |
|---|---|---|---|---|---|
| Voiceless | p | t | c | k | h |
| Voiced | b | d | j | g | |
| Nasal | m | n | | | |
| Liquid | | r, l | | | |
| Semivowel | w | y | | | |

The following table shows the vowel inventory of Middle Korean:| | Front | Central | Back |
|---|---|---|---|
| High | i | | u |
| Mid | e | | o |
| Low | a | | |

The Early Modern Korean Period (17th-19th centuries)

The Early Modern Korean period saw a number of significant sound changes, which brought the phonological system of Korean closer to that of the modern language. The most important of these changes were the loss of the voiced consonants and the merger of the mid vowels /e/ and /o/ into a single mid vowel /ə/. The following table shows the consonant inventory of Early Modern Korean:| | Labial | Dental/Alveolar | Palatal | Velar | Glottal |
|---|---|---|---|---|---|
| Voiceless | p | t | c | k | h |
| Voiced | | | | | |
| Nasal | m | n | | | |
| Liquid | | r, l | | | |
| Semivowel | w | y | | | |

The following table shows the vowel inventory of Early Modern Korean:| | Front | Central | Back |
|---|---|---|---|
| High | i | | u |
| Mid | | ə | |
| Low | a | | |

The Modern Korean Period (20th century to the present)

The Modern Korean period has seen relatively few phonological changes. The most notable change is the development of the diphthongs /ae/ and /oe/, which are now phonemic in all dialects of Korean. The following table shows the consonant inventory of Modern Korean:| | Labial | Dental/Alveolar | Palatal | Velar | Glottal |
|---|---|---|---|---|---|
| Voiceless | p | t | c | k | h |
| Voiced | b | d | j | g | |
| Nasal | m | n | | | |
| Liquid | | r, l | | | |
| Semivowel | w | y | | | |

The following table shows the vowel inventory of Modern Korean:| | Front | Central | Back |
|---|---|---|---|
| High | i | | u |
| Mid | e | | o |
| Low | a | | |
| Diphthongs | ae | | oe |

Conclusion

The historical phonology of Korean is a complex and fascinating subject. The sound system of Korean has undergone significant changes over the centuries, and these changes have had a major impact on the development of the modern language. The study of historical Korean phonology is essential for understanding the history of the Korean language and for reconstructing the Proto-Korean language.
