As a Korean language teacher, I often notice specific common Korean pronunciation mistakes when watching TV. Some mistakes may go unnoticed by others, but they stand out to me. One of the most frequent issues involves the pronunciation battle of 빗 vs 빚 vs 빛.
It’s surprisingly rare to hear someone pronounce all three correctly, especially in sequence. The core of the confusion is that these words can sound exactly the same one second, and completely different the next.
After reading this post, you’ll understand why this happens and how to master their pronunciation.

The Meaning of Each Word
Though these three words sound the same when used alone, their meanings are completely different:
- 빗 (bit): Comb
- 빚 (bit): Debt
- 빛 (bit): Light
It’s easy to mix them up, but knowing the meanings is key. However, if they all sound the same, how does context help? This brings us to the first secret of Korean pronunciation.
The Core Problem: Why Do 빗, 빚, and 빛 Sound the Same?
The main reason for the 빗 vs 빚 vs 빛 confusion is a rule called Batchim Neutralization (or “Rule of 7 Final Sounds”).
In Korean, when a consonant is in the final position of a syllable (the batchim), its sound gets “neutralized” to one of only seven possible sounds: [ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅇ].
The consonants ‘ㅅ’ (s), ‘ㅈ’ (j), and ‘ㅊ’ (ch) are not on this list. When they are in the final position, all of them are neutralized and pronounced as ‘ㄷ’ [t].
Therefore:
- 빗 (with a ‘ㅅ’ batchim) is pronounced [빋] (bit).
- 빚 (with a ‘ㅈ’ batchim) is pronounced [빋] (bit).
- 빛 (with a ‘ㅊ’ batchim) is pronounced [빋] (bit).
When spoken alone, they are 100% identical. This is why it’s a common Korean pronunciation mistake for learners to think they always sound the same. They don’t. Their hidden, true sounds are just waiting to be activated.
The Solution: The Korean Liaison Rule (연음법칙)
So, how do we “activate” their true sounds? By using the Korean liaison rule (연음법칙), or yeoneum beopchik.
In Korean, the consonant “ㅇ” is unique. When it’s at the beginning of a syllable (like in ‘을’ or ‘이’), it is a silent placeholder. It has no sound at all.
When a syllable ending in a batchim is followed by a syllable starting with the silent ‘ㅇ’, the batchim consonant “jumps over” and takes the ‘ㅇ’s place.
- Batchim + ㅇ -> The batchim’s original sound moves.
This is the magic key. The batchim is no longer in the final position, so the “neutralization” rule doesn’t apply. The consonant is now at the beginning of the next syllable, and its true sound is revealed.
Correct Pronunciation: 빗 vs 빚 vs 빛 Explained
Let’s add the object marker “을” (eul) and the subject marker “이” (i) to each of the three words and see how the pronunciation changes completely.
1. 빗 (Comb) -> The [s] Sound
The original sound of ‘ㅅ’ is [s]. When it moves, it keeps this sound.
- 빗을 (comb + eul) -> [비슬] (bi-seul)
- 빗이 (comb + i) -> [비시] (bi-si) (Note: ‘s’ + ‘i’ often becomes ‘shi’ in standard Korean)
2. 빚 (Debt) -> The [j] Sound
The original sound of ‘ㅈ’ is [j].
- 빚을 (debt + eul) -> [비즐] (bi-jeul)
- 빚이 (debt + i) -> [비지] (bi-ji)
3. 빛 (Light) -> The [ch] Sound
The original sound of ‘ㅊ’ is [ch].
- 빛을 (light + eul) -> [비츨] (bi-cheul)
- 빛이 (light + i) -> [비치] (bi-chi)
As you can see, the Korean pronunciation of 빗, 빚, and 빛 is totally different once a vowel is attached.
This is the correct way. However, many people (even native speakers) get lazy and mistakenly pronounce “빚을” and “빛을” as [비슬], the same as “빗을.”
Why This Mistake is So Common
This is one of the most common Korean pronunciation mistakes because the [s] sound of ‘빗’ is the “easiest” to make. It requires less effort than the [j] or [ch] sounds, which require more tension in the tongue. In casual, fast speech, speakers may default to the path of least resistance, pronouncing all three as [비슬].
While such pronunciation mistakes are minor in everyday conversations (as the meanings are clear from context), using correct pronunciation is still important, especially in formal settings.
Conclusion: Why Correct Pronunciation Matters
Just like a typo in an official document, making these errors in speech can affect how others perceive your professionalism or attention to detail.
This rule doesn’t just apply to 빗 vs 빚 vs 빛. It’s a fundamental part of the entire Korean language. Understanding the Korean liaison rule (연음법칙) will unlock your ability to pronounce everything more naturally.
So, next time you come across these words, try to remember their correct pronunciations. It’s a small step toward mastering more precise and polished Korean!
