# Korean Language

Korean (한국어, Hangugeo in the South; 조선말, Chosŏnmal in the North) is
the official language of both South Korea and North Korea. It is written
with a unique alphabet, marks social relationship directly in verb
endings, and has developed some real vocabulary differences between its
two national standards.

## Hangul: a designed featural alphabet

Korean is written in **Hangul** (한글 in the South, 조선글 Chosŏn'gŭl in
the North), a true alphabet of individual consonant and vowel letters —
not a syllabary and not a logographic system like Chinese characters.
It is unusual among the world's major writing systems for having been
deliberately designed and promulgated at a specific point in history
(commissioned under King Sejong in the 15th century), rather than
evolving gradually from an earlier script. Its letters are further
grouped visually into syllable blocks (e.g. ㅎ + ㅏ + ㄴ = 한), so a
Korean sentence looks block-by-block similar in rhythm to Chinese
characters even though each block decomposes into ordinary alphabetic
letters. Hanja (Chinese characters) still appear occasionally, mainly in
older texts, some newspapers, and for disambiguation, but ordinary
modern Korean text is written almost entirely in Hangul.

## Honorifics: jondaetmal vs. banmal

Korean grammatically encodes social relationship through a system of
speech levels, broadly split into:

- **Jondaetmal** (존댓말) — polite/honorific speech, used with
  strangers, elders, superiors, or anyone outside one's close in-group;
  realized through specific verb endings (-습니다/-요) and honorific
  vocabulary (e.g. 드시다 instead of 먹다 for "to eat" when referring to
  a respected person).
- **Banmal** (반말) — casual/informal speech, used with close friends,
  younger people, or children, dropping the honorific endings entirely.

Choice of level depends on the relative age, social status, and
closeness between speaker and listener, and getting it wrong — for
example using banmal with someone older or of higher status without an
established close relationship — reads as a genuine social error, not
merely an awkward style choice, comparable to being rude in person. When
translating or writing Korean, the appropriate level must be judged from
context (who is speaking to whom) rather than defaulted to one register
throughout.

## Word order and omission

Korean is subject-object-verb (SOV), with grammatical particles
attached to nouns to mark their role (topic, subject, object) rather
than relying on word order or prepositions the way English does.
As in Japanese, subjects and objects are frequently omitted entirely
when clear from context — a natural Korean sentence often states only
the verb, with speaker, listener, and topic all implied. Forcing every
pronoun into an English-style explicit sentence structure produces
noticeably unnatural Korean.

## South Korean vs. North Korean standard language

South Korean standard language (표준어, based on Seoul speech) and North
Korean standard language (문화어, munhwaŏ, based on P'yŏngyang speech)
have diverged over decades of political separation:

- Vocabulary differs notably in some domains, especially loanwords —
  South Korean has absorbed many English loanwords (아이스크림 for "ice
  cream") where North Korean prefers native or Sino-Korean
  coinages (얼음보숭이).
- Some spelling, spacing, and pronunciation conventions differ between
  the two standards' style guides.
- The two remain mutually intelligible overall, but a text written for
  one audience using its specific vocabulary can look foreign or dated
  to the other.

Default to South Korean standard usage unless a North Korean audience or
context is specified, since it is by far the more commonly requested
variety.

## Common pitfalls

- Using banmal (casual speech) toward an elder, stranger, or superior
  without an established close relationship — a real social error, not
  just a style mismatch.
- Mixing honorific and casual verb endings inconsistently within the
  same passage or conversation.
- Forcing explicit subject/object pronouns into every sentence when
  context already makes them clear, producing stilted, non-native text.
- Applying South Korean loanword-heavy vocabulary to a North Korean
  context, or vice versa, without checking the target standard.
- Confusing Hangul (the alphabet) with a syllabary or logographic
  script — each block is composed of separate alphabetic letters, not a
  single unanalyzable symbol per syllable.
