### Summary

Korean is the national language of both Koreas and a language isolate (Koreanic) with agglutinative morphology and elaborate speech-level honorifics. Hangul is praised as one of the world’s most efficient alphabets.

### Description

## Historical Evolution
Korean's genetic relations remain debated (Jeju dialect divergent; extinct Buyeo languages poorly attested). Middle Korean is documented from the 15th century; King Sejong's Hangul (1443) democratized literacy. Japanese occupation and national division produced modest lexical divergence North/South; both states maintain standardization institutes.

## Phonology
Korean has ten vowels in modern Seoul standard and a rich consonant system including tense, aspirated, and lax stops. Pitch accent existed historically but is marginal in contemporary Seoul speech. Liaison and tensification rules affect consonant clusters across morpheme boundaries.

## Syntax
Korean is SOV with postpositions and agglutinative verb endings stacking tense, aspect, mood, formality, and evidentiality. Honorifics alter verb forms and vocabulary (말씀 vs 말). Relative clauses precede nouns; subjects and objects are often dropped when recoverable from context.
