What is Korean?

Korean is a language isolate , meaning it has no confirmed direct genetic relationship with any other language. However, some scholars have suggested that Korean may have some historical connection with Altaic , Mongolian , or Japanese languages, but these hypotheses are not universally accepted.

Modern Korean uses a unique Korean writing system – Hunminjeongeum (now known as Hangul) , which was invented by King Sejong, the fourth monarch of the Joseon Dynasty, in 1443 and officially promulgated in 1446.

The origin and evolution of Korean

1. Proto-Korean period (before the 5th century BC)

The language spoken by the early inhabitants of the Korean Peninsula remains undocumented and is known as Proto-Korean .
It is speculated that the language of this period may have incorporated features of North Asian languages , such as a simple syllable structure and a predominantly subject-object-verb (SOV) word order.

• Geographical background: Korean Peninsula and Manchuria
• Linguistic characteristics: No clear evidence, mostly inferred from archaeology and place names

2. Ancient Korean Period (approximately 3rd century BC to 4th century AD)

The language of ancient Korea (the early period of the Three Kingdoms of Goguryeo, Baekje, and Silla) gradually formed a relatively stable structure.

• Goguryeo: Considered the main source of modern Korean
• Baekje and Silla: possibly different dialects or related languages ​​of Old Korean
• Writing system: At that time, the language was mainly recorded using ancient Chinese characters (called “li du” and “xiang zha”).

3. The Three Kingdoms Period and the Unified Silla Period (4th to 10th century AD)

After the Three Kingdoms period and the later unification of the peninsula by Silla, the languages ​​began to integrate further.

• Language features:
  • Forming a relatively fixed subject-object-verb (SOV) word order
  • The system of noun declension and verb change has become increasingly complex
• Writing style: Uses a lot of Chinese characters, but uses the liyue system to express the local language grammar

4. Goryeo Period (918-1392 AD)

The Goryeo Dynasty continued the cultural foundation of unified Silla, and the Korean language structure became more mature.

• Literary works such as Samguk Sagi and Samguk Yusa are written in Chinese, with Korean elements expressed through the ildu system.
• Social background: Chinese characters are used as the official language, and spoken Korean is popular among the people.

5. Joseon Dynasty and the Creation of Hunminjeongeum (15th century)

During the Joseon Dynasty (Lee Dynasty of Korea), major innovations in language and culture occurred.

• 1443: King Sejong the Great orders scholars to invent a writing system specifically for the Korean language – Hunminjeongeum
• 1446: The Hunminjeongeum Law was promulgated, marking the birth of Hangul
• Features:
  • The correspondence between letters and phonemes is clear, scientific and easy to learn
  • Emphasis on promoting literacy education so that the common people can also read and write

The creation of Hunminjeongeum enabled Korean to gradually move from relying on foreign characters (Chinese characters) to completely independent expression.

6. Modern Korean (19th century to present)

With the changes in modern society, Korean has also undergone a process of modernization and standardization.

• 1894: After the Sino-Japanese War Reforms, Korean was officially used in government documents
• Early 20th century: Korea experiences Japanese colonial rule, and the Korean language is suppressed
• After 1945: North and South Korea were divided, forming the South Korean Standard Language (based on the Seoul dialect) and the North Korean Standard Language (based on the Pyongyang dialect)

Modern Korean is gaining increasing international prominence, driven by global pop culture such as K-pop, Korean dramas, and Korean films.
