해요체 (polite informal)
The everyday polite speech style formed with -아요/-어요. Used with strangers, acquaintances and most classroom interaction; contrasts with formal 합니다체 and casual 반말.
합니다체 (formal polite)
The formal polite style using -ㅂ니다 (after vowels) and -습니다 (after consonants). Typical of announcements, news, presentations and formal conversation with superiors.
Nasalisation (비음화)
A sound rule where final ㄱ, ㄷ or ㅂ becomes ㅇ, ㄴ or ㅁ before ㄴ or ㅁ. Examples: 국물 → 궁물, 합니다 → 함니다. Essential for accurate listening.
Liquidisation (유음화)
When ㄴ meets ㄹ or ㄹ meets ㄴ, both become ㄹㄹ. Examples: 연락 → 열락, 신라 → 실라, 별로 → 별로. Affects how words sound in connected speech.
Native Korean numbers
하나, 둘, 셋, 넷, 다섯… used with counters for people (명), objects (개), age (살) and the hour (시). Often contract before counters: 한 명, 두 개, 세 시.
Sino-Korean numbers
일, 이, 삼, 사, 오… used for money (원), dates (년/월/일), minutes (분) and phone numbers. Never combined with native counters like 개 or 명.
Resyllabification (연음)
A final consonant moves to the next syllable when that syllable starts with a vowel. Example: 한국어 is pronounced 한구거, 옷이 is pronounced 오시.
Three-way consonant contrast
Korean stops occur as plain (ㄱ), tense (ㄲ) and aspirated (ㅋ). Tense is unaspirated with tight vocal folds; aspirated releases a strong puff of air.
Object particle 을/를
Marks the direct object of a verb. Use 을 after a consonant-final noun (밥을) and 를 after a vowel-final noun (사과를).
Topic particle 은/는
Marks the topic or contrast, not necessarily the grammatical subject. 은 after consonants, 는 after vowels: 저는 학생이에요.
Vowel harmony in -아요/-어요
Stems whose last vowel is ㅏ or ㅗ take -아요 (가다 → 가요); other stems take -어요 (먹다 → 먹어요). 하다 verbs contract to 해요.
Past tense -았/었어요
Adds past meaning to a verb or adjective stem with vowel harmony: 가다 → 갔어요, 먹다 → 먹었어요, 하다 → 했어요.
Future -(으)ㄹ 거예요
Expresses intention or prediction. Attach -ㄹ 거예요 to vowel-final stems and -을 거예요 to consonant-final stems: 갈 거예요, 먹을 거예요.
Honorific suffix -시-
Inserted before the verb ending when the subject is respected: 선생님께서 오세요. The particle 께서 replaces 이/가 for honored subjects.
Negation with 안 and 못
안 negates by choice or refusal (안 가요, I am not going); 못 negates ability (못 가요, I cannot go). Long forms: -지 않다 and -지 못하다.
Request form -(으)세요
A polite imperative used for instructions and requests: 앉으세요 (please sit), 읽으세요 (please read). Vowel-final stems take -세요.
Hangul syllable block
Each block combines an initial consonant, a vowel and an optional final consonant. Read top-to-bottom, left-to-right: 한 = ㅎ + ㅏ + ㄴ.
Double final consonants
겹받침 like ㄺ, ㄻ, ㄼ are pronounced as one sound in isolation: 값 → 갑, 삶 → 삼. Before a vowel, the second consonant links: 읽어 → 일거.
Tense consonant minimal pairs
Plain, tense and aspirated consonants distinguish words: 달 (moon) / 딸 (daughter) / 탈 (mask); 불 (fire) / 뿔 (horn) / 풀 (grass).
Demonstratives 이것/그것/저것
이것 is near the speaker, 그것 is near the listener, 저것 is far from both. Adjectival forms are 이, 그, 저 before a noun: 이 책, 그 책.
Connector 그래서
Means 'therefore' or 'so'. Signals a result or consequence in a sentence: 비가 와요. 그래서 우산을 써요.
Connector 하지만
Means 'but' or 'however'. Introduces a contrast with the previous clause: 한국어는 어려워요. 하지만 재미있어요.
Progressive -고 있다
Expresses an action in progress: 지금 책을 읽고 있어요 (I am reading a book now). Attach -고 있다 to the verb stem.
Counter 개
A counter for inanimate objects used with native Korean numbers: 한 개, 두 개, 세 개. Cannot be used with Sino-Korean numbers.
Spacing (띄어쓰기)
Korean writes spaces between words but keeps particles attached to their noun: 학교에 갑니다. Wrong spacing is a common writing error.
ㄷ irregular verbs
Verbs ending in ㄷ change ㄷ to ㄹ before a vowel ending: 듣다 → 들어요, 걷다 → 걸어요. But 받다 and 닫다 are regular.
ㅂ irregular verbs
Stems ending in ㅂ change to 우 or 오 before vowel endings: 춥다 → 추워요, 덥다 → 더워요, 돕다 → 도와요.
ㅅ irregular verbs
Stems ending in ㅅ drop the ㅅ before a vowel ending: 낫다 → 나아요, 짓다 → 지어요. Regular verbs like 벗다 keep the ㅅ.
르 irregular verbs
Stems ending in 르 double the ㄹ and add ㄹ before vowel endings: 모르다 → 몰라요, 빠르다 → 빨라요.
Hangul spelling vs sound
Standard orthography reflects the base form, not pronunciation. Write 감사합니다 even though it sounds 감삼니다; write 국물, not 궁물.
Date and time format
Dates run from largest to smallest unit: 2024년 5월 3일. Times use native numbers for the hour and Sino-Korean for minutes: 오후 세 시 삼십 분.
ㅎ irregular verbs
Stems ending in ㅎ drop the ㅎ before vowel endings: 그렇다 → 그래요, 하얗다 → 하얘요. Before ㄴ or ㄹ the ㅎ is silent.
