Major Rules and Examples of Standard Korean Pronunciation

The Standard Korean Pronunciation Rules, established in 1988, aim to reflect actual standard language pronunciation while considering the tradition and logic of the Korean language. This regulation consists of seven chapters and thirty articles. Instead of covering all of them, we will introduce 14 essential pronunciation rules frequently used in daily life, along with examples.

1. 비음화 (Nasalization)

Nasalization is a phonological phenomenon where certain consonants change into nasal sounds like “ㄴ,” “ㅁ,” or “ㅇ.” It mainly occurs when a final consonant precedes a nasal sound. This change ensures smoother and more natural pronunciation.

 

📌 Example Usage

• 국물 → [궁물] (broth → [goong-mul])

• 앞마당 → [암마당] (front yard → [am-ma-dang])

• 밥물 → [밤물] (rice water → [bam-mul])

• 깎는 → [깡는] (cutting → [kkang-neun])

• 먹는 → [멍는] (eating → [meong-neun])

• 닫는 → [단는] (closing → [dan-neun])

 

2. 유음화 (Liquidization)

Liquidation refers to a change in pronunciation influenced by the liquid consonant “ㄹ.” It usually occurs when “ㄴ” appears before or after “ㄹ”, often changing to “ㄹ” itself. This adjustment helps maintain the natural flow of speech.

 

📌 Example Usage

• 전라도 → [절라도] (Jeolla Province → [jeol-la-do])

• 신라 → [실라] (Silla Dynasty → [sil-la])

• 한라산 → [할라산] (Mount Halla → [hal-la-san])

• 칼날 → [칼랄] (blade → [kal-lal])

 

3. 된소리되기 (Fortis or Tense Sounding)

This rule involves a consonant becoming a tense sound (fortis) when combined with another consonant, especially at the end of a syllable. It often changes soft consonants (ㄱ, ㄷ, ㅂ, ㅈ) into their tense counterparts (ㄲ, ㄸ, ㅃ, ㅉ, ㅆ) for added pronunciation strength.

 

📌 Example Usage

• 국밥 → [국빱] (rice soup → [guk-ppap])

• 국자 → [국짜] (ladle → [guk-jja])

• 학교 → [학꾜] (school → [hak-kyo])

• 닭장 → [닥짱] (chicken coop → [dak-jjang])

• 꽃병 → [꼳뼝] (flower vase → [kkot-ppyeong])

• 믿지 → [믿찌] (don’t trust → [mit-jji])

• 안고 → [안꼬] (hugging → [an-kko])

• 감다 → [감따] (close [eyes] / wash [hair] → [gam-tta])

• 갈등 → [갈뜽] (conflict → [gal-tteung])

• 일시 → [일씨] (temporary → [il-ssi])

• 옷고름 → [옫꼬름] (garment tie → [ot-kko-reum])

 

4. 구개음화 (Palatalization)

Palatalization occurs when “ㄷ” and “ㅌ” are followed by the vowel “ㅣ”, causing them to change into “ㅈ” and “ㅊ”, respectively.

 

📌 Example Usage

• 굳이 → [구지] (if you insist → [gu-ji])

• 같이 → [가치] (together → [ga-chi])

• 해돋이 → [해도지] (sunrise → [hae-do-ji])

• 미닫이 → [미다지] (sliding door → [mi-da-ji])

• 붙이다 → [부치다] (to stick, to attach → [bu-chi-da])

• 맏이 → [마지] (eldest child → [ma-ji])

• 밭이 → [바치] (field → [ba-chi])

• 끝이 → [끄치] (the end → [kkeu-chi])

 

5. 거센소리되기 (Aspirated Sound Shift)

The aspirated sound shift occurs when “ㅎ” combines with certain consonants such as “ㄱ,” “ㄷ,” “ㅂ,” or “ㅈ,” changing them to their aspirated forms: “ㅋ,” “ㅌ,” “ㅍ,” and “ㅊ.” This change enhances pronunciation clarity in Korean phonology.

 

📌 Example Usage

• 놓고 → [노코] (put and → [no-ko])

• 밟히다 → [발피다] (to be stepped on → [bal-pi-da])

• 막히다 → [마키다] (to be blocked → [ma-ki-da])

• 잡히다 → [자피다] (to be caught → [ja-pi-da])

• 꽃하고 → [꼬타고] (with flowers → [kko-ta-go])

• 좋고 → [조코] (good and → [jo-ko])

• 많다 → [만타] (to be many → [man-ta])

• 닫히다 → [다치다] (to be closed → [da-chi-da])

• 업히다 → [어피다] (to be carried on the back → [eo-pi-da])



6. 두음 법칙 (Initial Sound Rule)

The Initial Sound Rule refers to the phonological phenomenon where certain consonants are either not pronounced or changed when they appear at the beginning of a word. This rule, mainly affecting Sino-Korean words, prevents “ㄴ” and “ㄹ” from occurring at word-initial positions, often altering the word form.

 

📌 Example Usage

• 여자 (女子) ← 녀자: [여자] (woman → [yeo-ja])

• 요금 (料金) ← 뇨금: [요금] (fare, fee → [yo-geum])

• 연세대학교 ← 년세대학교: [연세대학교] (Yonsei University → [yeon-se dae-hak-gyo])

• 노인 (老人) ← 로인: [노인] (elderly person → [no-in])

• 내일 (來日) ← 래일: [내일] (tomorrow → [nae-il])

• 역사 (歷史) ← 력사: [역사] (history → [yeok-sa])

• 이과 (理科) ← 리과: [이과/이꽈] (science track → [i-gwa]/[i-kkwa])

• 요리 (料理) ← 료리: [요리] (cooking → [yo-ri])

 

7. 모음 탈락 (Vowel Elision)

Vowel elision occurs when two vowels appear consecutively and one is dropped to ease pronunciation. This typically happens when verb stems and endings combine, altering the word form according to specific rules.

 

🐾 Stem: the unchanging part of a conjugated word, e.g., “보-” in 보다/보니/보고 or “먹-” in 먹다/먹니/먹고.

🐾 Ending: the changing part added to the stem, e.g., “-다”, “-으며”, “-고” in 점잖다/점잖으며/점잖고.

 

📌 Example Usage

① 동일 모음 탈락 (Identical Vowel Elision): When the final vowel of the stem and the initial vowel of the ending are the same, one of them is dropped.

• 가 + 아 → 가: [가] (to go → [ga])

• 서 + 어도 → 서도: [서도] (even if you stand → [seo-do])

• 만나 + 았고 → 만났고: [만낟꼬] (met and → [man-nat-kko])

 

② “ㅡ” 탈락 (“ㅡ” Elision): When the final vowel of the stem is “ㅡ” and it is followed by an ending that begins with a vowel, the “ㅡ” is dropped.

• 크 + 어서 → 커서: [커서] (because it’s big → [keo-seo])

• 예쁘 + 어도 → 예뻐도: [예뻐도] (even if pretty → [ye-ppeo-do])

 

③ “ㅏ/ㅓ” 탈락 (“ㅏ” or “ㅓ” Elision): When the final vowel of the stem is “ㅏ” or “ㅓ” and the following ending begins with “ㅏ” or “ㅓ”, one of them is dropped.

• 서 + 어 → 서: [서] (to stand → [seo])

• 가 + 아 → 가: [가] (to go → [ga])



8. 반모음 첨가 (Semivowel Insertion)

Semivowel insertion happens when a gliding sound (ㅣ→y, ㅗ/ㅜ→w) is added between two vowels for smoother pronunciation. This may change the actual word form (e.g., “와”, “줘”) or simply affect the pronunciation (e.g., “피어” [피여], “되어” [되여]).

 

📌 Example Usage

• 오 + 아 → 와: [와] (come and → [wa])

• 주 + 어 → 줘: [줘] (give → [jwo])

• 피 + 어 → 피어: [피여] (blooms → [pi-yeo])

• 되 + 어 → 되어: [되여] (becomes → [dwe-yeo])

• 이 + 오 → 이오: [이요] (it is [formal ending] → [i-yo])

• 아니 + 오 → 아니오: [아니요] (no → [a-ni-yo])

• 두 + 어 → 둬: [둬] (put it → [dwo])

 

9. 연음 법칙 (Liaison Rule)

The liaison rule in Korean refers to a phonological phenomenon where one syllable's final consonant (받침) moves to the initial position of the following syllable when it starts with a vowel. This rule plays a crucial role in achieving smooth and natural pronunciation in Korean.

 

📌 Example Usage

① 홑받침의 경우 (Single Final Consonant)

• 꽃 + 이 → 꽃이: [꼬치] (flower + subject particle → [kko-chi])

• 밥 + 을 → 밥을: [바블] (rice + object particle → [ba-beul])

• 책 + 이 → 책이: [채기] (book + subject particle → [chae-gi])

 

② 쌍받침의 경우 (Double Consonants as One Sound)

• 있어: [이써] (there is → [i-sseo])

• 갔어: [가써] (went → [ga-sseo])

• 깎이다: [까끼다] (to be shaved or trimmed → [kka-kki-da])

 

🐾 Double 받침: when the final consonant of a syllable is written as a doubled letter, only one is pronounced, e.g., “ㄲ,” “ㅆ.”

 

③ 겹받침의 경우 (Clustered Final Consonants)

• 넋 + 이 → 넋이: [넉씨] (soul + subject particle → [neok-ssi])

• 값 + 이 → 값이: [갑씨] (price + subject particle → [gap-ssi])

• 값 + 어치 → 값어치: [가버치] (worth of value → [ga-beo-chi])

 

🐾 Clustered 받침: when two different consonants are written in the final position. Usually, only the first is pronounced unless influenced by the next syllable. Examples include “ㄳ, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, ㄽ, ㄾ, ㄿ, ㅀ, ㅄ.”

 

10. 모음 조화 (Vowel Harmony)

Vowel harmony refers to the tendency for positive vowels to pair with other positive vowels and dark vowels with other dark vowels. This pattern frequently occurs between verb stems and endings or affixes, enhancing pronunciation consistency and clarity of meaning.

 

📌 Example Usage

• 깊다 + 어 → 깊어: “ㅡ” + “ㅓ”, 음성모음끼리 조화되어 [기퍼]로 발음됩니다.

(deep + connective ending → [gi-peo])

• 짧다 + 아 → 짧아: “ㅏ” + “ㅏ”, 양성모음끼리 조화되어 [짤바]로 발음됩니다.

(short + connective ending → [jjal-ba])

• 굵다 + 어 → 굵어: “ㅜ” + “ㅓ”, 음성모음끼리 조화되어 [굴거]로 발음됩니다.

(thick + connective ending → [gul-geo])

 

🐾 Bright vowels, pronounced with a wide mouth and a light tone: “ㅏ, ㅑ, ㅗ, ㅘ, ㅚ.”

🐾 Dark vowels, pronounced with a narrow mouth and a heavier tone: “ㅓ, ㅕ, ㅜ, ㅠ, ㅟ, ㅡ.”

🐾 Neutral vowel: “ㅣ” is neither bright nor dark.

 

Vowel harmony is also prominent in onomatopoeia and mimetic words.

📌 의성어의 모음조화 사례 (Onomatopoeia Examples)

• 살랑살랑 (gentle wind sound)

• 앙앙 (crying sound)

• 졸졸 (flowing water sound)

• 찰찰 (splashing water)

• 깔깔 (laughing sound)

 

📌 의태어의 모음조화 사례 (Mimetic Word Examples)

• 알록달록 (colorful appearance)

• 아장아장 (baby’s waddling steps)

• 설렁설렁 (leisurely movement)

• 얼룩덜룩 (uneven coloring)

• 어정어정 (slow, heavy walk)

11. 음절의 끝소리 규칙 (Final Consonant Neutralization)

The final consonant neutralization rule limits final syllable consonants in Korean to one of seven sounds: “ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅇ”. When other consonants appear at the end of a syllable, they are pronounced as one of these seven.

 

📌 Example Usage

• 밖 → [박]: “ㄲ”이 “ㄱ”으로 바뀌어 발음됩니다. (outside → [bak])

• 꽃 → [꼳]: “ㅊ”이 “ㄷ”으로 바뀌어 발음됩니다. (flower → [kkot])

• 낫 → [낟]: “ㅅ”이 “ㄷ”으로 바뀌어 발음됩니다. (sickle → [nat])

• 잎 → [입]: “ㅍ”이 “ㅂ”으로 바뀌어 발음됩니다. (leaf → [ip])

 

12. “ㄴ” 첨가 (Insertion of “ㄴ”)

Insertion of “ㄴ” occurs in compound or derived words when the first element ends in a consonant and the following element starts with “이, 야, 여, 요, 유”. In these cases, a linking “ㄴ” sound is inserted between the two.

 

📌 Example Usage

• 솜이불 → [솜니불] (cotton blanket → [som-ni-bul])

• 꽃잎 → [꼰닙] (flower petal → [kkon-nip])

• 맨입 → [맨닙] (bare mouth → [maen-nip])

• 한여름 → [한녀름] (midsummer → [han-nyeo-reum])

• 색연필 → [생년필] (colored pencil → [saeng-nyeon-pil])

 

13. 사잇소리 현상 (Interfixation / Double Consonant Phenomenon)

The 사잇소리 현상 (inter-fixation phenomenon) is a unique phonological feature in Korean. It occurs when two words are combined to form a compound word and has the following characteristics:
- When the final sound of the first word is resonant (a vowel, “ㄴ,” “ㄹ,” “ㅁ,” or “ㅇ”) and the first sound of the second word is a plain voiceless consonant, that consonant becomes a tense sound.
- When the first word ends in a vowel and the second word begins with “ㅁ” or “ㄴ,” an additional “ㄴ” sound is inserted at the end of the first word.
- When the second word begins with “ㅣ” or the glide “y”, an “ㄴ” sound is added between the final sound of the first word and the initial sound of the second.

 

Interfixation occurs in Korean compound words, causing sound changes that increase fluency and sometimes alter meaning.

 

📌 Example Usage

- 된소리 첨가 (Tense Sound Addition)

• 산길 → [산낄] (mountain path → [san-kil])

• 봄비 → [봄삐] (spring rain → [bom-pi])

• 손가락 → [손까락] (finger → [son-kka-rak])

 

- “ㄴ” 첨가 (Insertion of “ㄴ” between vowel-ending and nasal-starting syllables)

• 아래 + 마을 → 아랫마을 → [아랜마을] (lower village → [a-raen-ma-eul])

• 코 + 날 → 콧날 → [콘날] (bridge of the nose → [kon-nal])

• 바다 + 물 → 바닷물 → [바단물] (sea water → [ba-dan-mul])

 

- “ㄴ” 첨가 (When following syllable begins with “ㅣ” or a glide “y”)

• 나무 + 잎 → 나뭇잎 → [나문닙] (tree leaf → [na-mun-nip])

• 아래 + 이 → 아랫니 → [아랜니] (lower tooth → [a-raen-ni])

 

14. “ㅎ” 탈락 (“ㅎ” Deletion)

“ㅎ” deletion occurs when a verb/adjective stem ending in “ㅎ” combines with a grammatical ending or suffix starting with a vowel. In this case, the “ㅎ” sound disappears.

 

📌 Example Usage

• 낳다 + 아 → 낳아: [나아] (to give birth → [na-a])

• 쌓다 + 이다 → 쌓이다: [싸이다] (to be piled up → [ssa-i-da])

• 끓다 + 이다 → 끓이다: [끄리다] (to boil something → [kkeu-ri-da])

• 많다 + 아 → 많아: [마나] (to be many → [ma-na])

• 놓다 + 아서 → 놓아서: [노아서] (put and → [no-a-seo])
