1. Formal Polite Style (격식체 — 하십시오체)
Formal polite (often known as 하십시오체 or 합니다 style) represents the highest level of respect and formality in modern Korean.
- News broadcasting, military, and official television announcements.
- Business presentations, corporate conferences, and job interviews.
- Addressing elders, first-time business partners, or high-status clients.
Present Tense Conjugation Rules:
- Stem ends with a batchim (final consonant): Stem +
-습니다(Statement) /-습니까?(Question). - Stem ends with a vowel (no batchim): Stem +
-ㅂ니다(Statement) /-ㅂ니까?(Question). - Nouns: Noun +
-입니다(Statement) /-입니까?(Question). - Formal Command: Stem +
-(으)십시오(Please do...). - Formal Proposal: Stem +
-(으)ㅂ시다(Let us do...).
Stems ending in
ㄹ (e.g. 살다, 만들다, 알다) lose their ㄹ before ㅂ: 살다 ➔ 살 + ㅂ니다 ➔ 삽니다 (I live); 만들다 ➔ 만듭니다 (To make). Practical Examples:
| Root Verb/Adj | Declarative (Statement) | Interrogative (Question) | English Meaning | Audio |
|---|---|---|---|---|
| 가다 (To go) | 갑니다 | 갑니까? | Go / Are you going? | |
| 먹다 (To eat) | 먹습니다 [먹씀니다] | 먹습니까? | Eat / Are you eating? | |
| 살다 (To live) | 삽니다 | 삽니까? | Live / Do you live there? | |

| 앉다 (To sit) | 앉으십시오 (Command) | 앉읍시다 (Proposal) | Please sit down / Let us sit |
2. Informal Polite (해요체) & Casual Banmal (반말)
Informal polite is the backbone of daily conversational Korean (accounting for over 80% of spoken Korean). It balances friendly warmth with genuine respect.
A. Informal Polite (해요체): Everyday conversational standard
- Last vowel is ㅏ or ㅗ (bright vowels): Attach
-아요. (가다 ➔ 가요; 보다 ➔ 봐요; 살다 ➔ 살아요) - Last vowel is NOT ㅏ or ㅗ (dark/neutral vowels ㅓ, ㅜ, ㅣ, ㅡ, ㅐ...): Attach
-어요. (먹다 ➔ 먹어요; 마시다 ➔ 마셔요; 배우다 ➔ 배워요) - Verbs ending in 하다: Always becomes
해요. (공부하다 ➔ 공부해요; 일하다 ➔ 일해요) - Nouns: Batchim +
-이에요| Vowel +-예요. (의사예요; 선생님이에요)
- ㅂ-Irregular: The
ㅂtransforms into우before vowels, then attaches어요➔워요. (춥다 ➔ 추워요 [cold], 어렵다 ➔ 어려워요 [difficult]. Exception: 돕다 ➔ 도와요 [to help]). - ㄷ-Irregular: The
ㄷchanges intoㄹwhen followed by a vowel. (듣다 ➔ 들어요 [to listen], 걷다 ➔ 걸어요 [to walk]). - 르-Irregular: Doubles the
ㄹto the preceding syllable, then adds라/러. (모르다 ➔ 몰라요 [not know], 빠르다 ➔ 빨라요 [fast]). - ㅡ-Irregular: The vowel
ㅡdrops when followed by a vowel ending. (크다 ➔ 커요 [big], 쓰다 ➔ 써요 [write/use], 예쁘다 ➔ 예뻐요 [pretty]).
B. Casual Banmal Style (반말 — Non-honorific / Casual):
Only for close friends of the same age, younger persons, children, or self-soliloquy. Never use with strangers, superiors, or business associates!
요 from the 해요체 form!가요 ➔ 가 | 먹어요 ➔ 먹어 | 공부해요 ➔ 공부해 | 예뻐요 ➔ 예뻐.

4. Standard Pronunciation & 7 Core Sound Change Rules
Korean pronunciation relies on natural phonological assimilation rules for effortless flow of speech. Master these 7 rules to sound like a native announcer!
A. The 7 Final Batchim Representative Sounds
Rule: 받침 (Patchim) ➔ 7 Representative Sounds:
| Audio | Patchim | Practical Examples | Play |
|---|---|---|---|
| [ㄱ] | ㄱ, ㅋ, ㄲ, ㄳ, ㄺ | 수박 [수박], 부엌 [부억], 밖 [박], 닭 [닥] | |
| [ㄴ] | ㄴ, ㄵ, ㄶ | 눈 [눈], 편지 [편지], 앉다 [안따], 많다 [만타] | |
| [ㄷ] | ㄷ, ㅅ, ㅈ, ㅊ, ㅌ, ㅎ, ㅆ | 옷 [옫], 낮 [낟], 꽃 [꼳], 끝 [꾿], 있다 [읻따] | |
| [ㄹ] | ㄹ, ㄼ, ㄽ, ㄾ, ㅀ | 달 [달], 물 [물], 넓다 [널따], 핥다 [할따] | |
| [ㅁ] | ㅁ, ㄻ | 봄 [봄], 마음 [마음], 삶 [삼] | |
| [ㅂ] | ㅂ, ㅍ, ㅄ, ㄿ | 밥 [밥], 잎 [입], 값 [갑], 읊다 [읍따] | |
| [ㅇ] | ㅇ | 강 [강], 방 [방], 공항 [공항] |
B. The 7 Essential Sound Assimilation Rules:
1. Linking / Liaison (연음화)
When a syllable with a final consonant (batchim) is followed by a syllable starting with a vowel (silent ㅇ), the final consonant shifts to become the initial sound of the next syllable.
• 한국어 ➔ [한구거]
• 음악 ➔ [으막]
• 읽어요 ➔ [일거요]
• 앉아요 ➔ [안자요]
2. Tensification (경음화)
When plain stops [ㄱ, ㄷ, ㅂ] meet initial consonants [ㄱ, ㄷ, ㅂ, ㅅ, ㅈ], the following consonant becomes tensed [ㄲ, ㄸ, ㅃ, ㅆ, ㅉ].
• 학교 ➔ [학꾜]
• 식당 ➔ [식땅]
• 잡지 ➔ [잡찌]
• 국수 ➔ [국쑤]
3. Nasalization (비음화)
Stops [ㄱ, ㄷ, ㅂ] before nasal consonants [ㄴ, ㅁ] turn into nasal equivalents [ㅇ, ㄴ, ㅁ]. Liquids [ㄹ] following consonants turn into [ㄴ].
• 한국말 ➔ [한궁말]
• 감사합니다 ➔ [감사함니다]
• 십년 ➔ [심년]
• 국립 ➔ [궁닙]
• 음료수 ➔ [음뇨수]
4. Liquidization (유음화)
When nasal [ㄴ] meets liquid [ㄹ] (in either order), both assimilate into the liquid sound [ㄹ] (pronounced like an English L).
• 신라 ➔ [실라]
• 연락 ➔ [열락]
• 설날 ➔ [설랄]
• 칼날 ➔ [칼랄]
5. Aspiration (격음화)
When plain stops [ㄱ, ㄷ, ㅂ, ㅈ] collide with [ㅎ], they merge into strong aspirated consonants [ㅋ, ㅌ, ㅍ, ㅊ].
• 축하 ➔ [추카]
• 좋다 ➔ [조타]
• 입학 ➔ [이팍]
• 맞히다 ➔ [마치다]
6. Palatalization (구개음화)
When batchim [ㄷ, ㅌ] is followed by vowel [이], it transforms into the palatal sounds [ㅈ, ㅊ].
• 같이 ➔ [가치]
• 굳이 ➔ [구지]
• 붙이다 ➔ [부치다]
• 밭이 ➔ [바치]
7. Silent & Weakened H (ㅎ 탈락 / 약화)
The consonant [ㅎ] between voiced sounds or before vowels becomes silent or barely audible.
• 좋아요 ➔ [조아요]
• 많이 ➔ [마니]
• 넣어 ➔ [너어]
• 괜찮아요 ➔ [괜차나요]
