You’ve learned Hangul. You can read every character. But when you try to pronounce Korean words, something feels… off. Why does 받침 sound like “bat-chim” and not “bat-chip”?
Welcome to batchim rules (받침)—the pronunciation patterns that make spoken Korean sound natural.
What Is Batchim?
Batchim (받침) literally means “supporting floor” or “foundation.” In Korean linguistics, it refers to the final consonant at the bottom of a Hangul syllable block.
Look at this syllable: 한
- ㅎ = initial consonant
- ㅏ = vowel
- ㄴ = batchim (final consonant)
Not all syllables have batchim. Compare:
- 가 (ga) - no batchim
- 감 (gam) - has batchim (ㅁ)
Why Batchim Rules Matter for Reading Korean
Here’s the problem most Korean learners face:
You can identify each Hangul character individually. You know ㄱ makes a “g” or “k” sound, and ㄴ makes an “n” sound. But you don’t know how to pronounce them when they interact with the next syllable.
This is why Korean sounds “mumbly” or unclear to beginners—native speakers are applying batchim sound change rules automatically at lightning speed, and you’re not catching it.
Example comparison:
| Written | Beginner Reading | Native Pronunciation | Why? |
|---|---|---|---|
| 한국말 | han-guk-mal | hang-gung-mal | Nasalization + tensification |
| 받침 | bat-chim | bat-chim | No change (lucky!) |
| 입니다 | ip-ni-da | im-ni-da | Nasalization (ㅂ → ㅁ) |
| 좋다 | jot-da | jo-ta | Aspiration (ㅎ + ㄷ → ㅌ) |
See the difference? That’s batchim rules transforming pronunciation—and it happens in almost every Korean sentence.
Why English Speakers Struggle with Batchim
If you speak English, batchim is counterintuitive because:
- English releases final consonants - We say “CAT” with a clear T sound
- Korean stops them short - 밧 ends with your tongue in position but no air release
- English consonants don’t change - “Goodbye” is always pronounced the same
- Korean consonants transform - ㄱ might become ㅇ, ㄴ, or ㅋ depending on what follows
Your brain is wired for English phonetics. Batchim requires rewiring.
The 7 Batchim Consonant Sounds
Here’s something crucial: while Korean has 27 possible batchim letters, they only produce 7 distinct sounds when pronounced:
| Batchim Letters | Sound | Example |
|---|---|---|
| ㄱ, ㅋ, ㄲ | [k] | 밖 (bakk) |
| ㄴ | [n] | 눈 (nun) |
| ㄷ, ㅌ, ㅅ, ㅆ, ㅈ, ㅊ, ㅎ | [t] | 꽃 (kkot) |
| ㄹ | [l] (or [r] initially) | 말 (mal) |
| ㅁ | [m] | 밤 (bam) |
| ㅂ, ㅍ | [p] | 밥 (bap) |
| ㅇ | [ng] | 강 (gang) |
Note: ㄹ is pronounced [l] as a final consonant (batchim), but [r] when it starts a syllable (like in 라면 ramyeon).
This is the first batchim rule to memorize: Multiple consonants can produce the same final sound.
Batchim Pronunciation Rules
Now for the important part: what happens when a batchim meets the next syllable?
Rule 1: Liaison (연음)
When a batchim is followed by a vowel (ㅇ), the consonant moves to the next syllable.
Examples:
| Written | Pronunciation | Translation |
|---|---|---|
| 한글 | [han-geul] | Hangul |
| 음악 | [eu-mak] | music |
| 읽어요 | [il-geo-yo] | (I) read |
Why it happens: Korean avoids ending words with strong consonants, so they flow into the next syllable when possible.
Rule 2: Nasalization (비음화)
When a stop consonant (ㄱ, ㄷ, ㅂ) meets a nasal consonant (ㄴ, ㅁ), it becomes nasal too.
Transformations:
- ㄱ → ㅇ (before ㄴ, ㅁ)
- ㄷ → ㄴ (before ㄴ, ㅁ)
- ㅂ → ㅁ (before ㄴ, ㅁ)
Examples:
| Written | Pronunciation | Translation |
|---|---|---|
| 학년 | [hang-nyeon] | school year |
| 받는 | [ban-neun] | receiving |
| 입니다 | [im-ni-da] | (it) is |

Rule 3: Tensification (경음화)
After certain consonants, the following consonant becomes “tense” (doubled).
Examples:
| Written | Pronunciation | Translation |
|---|---|---|
| 학교 | [hak-kkyo] | school |
| 꽃다발 | [kkot-tta-bal] | bouquet |
| 국밥 | [guk-ppap] | rice soup |
Rule 4: Aspiration (격음화)
When ㅎ meets certain consonants, they merge into aspirated consonants (ㅋ, ㅌ, ㅍ, ㅊ).
Examples:
| Written | Pronunciation | Translation |
|---|---|---|
| 좋다 | [jo-ta] | good |
| 입학 | [i-pak] | entrance |
| 축하 | [chu-ka] | congratulations |
Rule 5: Palatalization (구개음화)
When ㄷ or ㅌ meets the vowel 이, it changes to ㅈ or ㅊ.
Examples:
| Written | Pronunciation | Translation |
|---|---|---|
| 같이 | [ga-chi] | together |
| 굳이 | [gu-ji] | insistently |
| 해돋이 | [hae-do-ji] | sunrise |
Why Most Learners Struggle with Batchim

Common Batchim Mistakes
Mistake 1: Pronouncing Every Letter
Wrong: 학교 as “hak-gyo” Right: 학교 as “hak-kkyo” (tensification)
Mistake 2: Ignoring Sound Changes
Wrong: 입니다 as “ip-ni-da” Right: 입니다 as “im-ni-da” (nasalization)
Mistake 3: Over-Releasing Final Consonants
In English, we release final consonants strongly (“cat” with a hard T). Korean batchim is unreleased—your mouth gets ready for the sound but doesn’t fully pronounce it.
Practice Batchim with Real Words
Here are common Korean words that use different batchim rules. Try reading them:
Liaison:
- 먹어요 (meo-geo-yo) - (I) eat
- 좋아요 (jo-a-yo) - (I) like
Nasalization:
- 감사합니다 (gam-sa-ham-ni-da) - thank you
- 십만 (sim-man) - 100,000
Tensification:
- 국가 (guk-kka) - nation
- 학생 (hak-ssaeng) - student
Aspiration:
- 좋아 (jo-a) - good
- 입학생 (i-pak-ssaeng) - new student
Palatalization:
- 같이 (ga-chi) - together
- 맏이 (ma-ji) - eldest

Common Questions About Batchim Rules
What are batchim rules in Korean?
Batchim rules (받침 규칙) are the pronunciation patterns that determine how final consonants (batchim) change their sound when they meet the next syllable. There are 5-7 main batchim rules in Korean, including liaison, nasalization, tensification, aspiration, and palatalization. These rules make spoken Korean sound fluid and natural.
How many batchim sounds are there?
While there are 27 possible batchim consonants in Korean, they only produce 7 distinct sounds:
- [k] - ㄱ, ㅋ, ㄲ
- [n] - ㄴ
- [t] - ㄷ, ㅌ, ㅅ, ㅆ, ㅈ, ㅊ, ㅎ
- [l] - ㄹ
- [m] - ㅁ
- [p] - ㅂ, ㅍ
- [ng] - ㅇ
This simplification is the first batchim rule beginners should memorize.
Why is batchim so hard for English speakers?
Batchim is hard for English speakers because:
- English releases final consonants, Korean stops them
- English consonants stay stable, Korean consonants transform based on context
- Sound changes happen automatically and fast—natives don’t consciously think about them
- English has fewer sound change rules overall
Your English-trained brain expects stability, but batchim is all about fluidity and transformation.
Do I really need to learn batchim rules?
Yes, absolutely. Without batchim rules:
- Your pronunciation will sound unnatural and choppy
- Native speakers may struggle to understand you
- You won’t understand natives because they use these rules automatically
- Your reading speed will remain slow (letter-by-letter)
- K-dramas and K-pop will sound “mumbly” and unclear
Batchim rules are non-negotiable for fluency.
What’s the most common batchim rule?
Liaison (연음) is probably the most common, appearing whenever a syllable ending in a consonant is followed by a syllable starting with ㅇ (vowel). The consonant simply “moves” to the next syllable. Example: 먹어요 becomes [meo-geo-yo], not [meok-eo-yo].
How long does it take to master batchim rules?
With focused daily practice, most learners can:
- Understand the rules: 1-2 weeks
- Recognize them in slow speech: 2-4 weeks
- Apply them automatically: 2-3 months
- Master them at native speed: 6-12 months
The key is consistent practice with immediate feedback—which is exactly what the Batchim app provides.
Can I just ignore batchim rules and still speak Korean?
You can technically speak Korean without batchim rules, but you’ll sound like a robot reading letter-by-letter. Imagine if someone spoke English by carefully enunciating every letter: “Good-d-bye” instead of “Goodbye.” That’s how you’ll sound. Plus, you won’t understand natives who use these rules automatically.
What’s the difference between batchim and final consonants?
“Batchim” (받침) and “final consonant” mean the same thing—they both refer to the consonant at the bottom of a Korean syllable block. “Batchim” is the Korean linguistics term, while “final consonant” is the English translation. Most Korean language resources use “batchim” because it’s shorter and more precise.
How Batchim Rules Improve Your Reading Speed
Once you internalize batchim rules, something magical happens: you stop reading letter-by-letter.
Instead of seeing individual components:
ㅎ…ㅏ…ㄱ…ㄱ…ㅛ… (5 separate pieces)
Your brain instantly recognizes:
학교 (school!)
This is called chunking—your brain recognizes syllables and words as single units. It’s the difference between reading at 45 characters per minute (beginner) and 135 CPM (intermediate) or 200+ CPM (advanced).
Real impact on reading speed:
- Without batchim rules: You read 한국 사람입니다 in ~3-4 seconds
- With batchim rules: You read it in ~1 second (native speed)
That’s 3-4x faster reading, just from mastering sound patterns.
Next Steps: Master Batchim
Batchim rules are the missing piece between knowing Hangul and reading Korean fluently. Once you master them:
✅ Korean pronunciation makes sense ✅ You can read K-pop lyrics accurately ✅ K-dramas sound less “mumbly” ✅ Your reading speed doubles or triples
The fastest way to master batchim? Targeted practice with immediate feedback.
That’s exactly what the Batchim app does. Our drills are specifically designed to train batchim recognition until it becomes automatic.
