Korean Liaison: Linking Sounds Across Syllables (연음)
When Korean is spoken naturally, words do not stop and restart between syllables. Instead, sound flows in a continuous wave through a phonetic principle known as yeoneum or sound linking. When a syllable with batchim meets an empty vowel syllable, the consonant slides across smoothly.

How the Liaison Rule Operates
In Hangul, the initial consonant circle ㅇ is phonetically silent when it stands at the start of a syllable block, representing an open doorway. When a preceding syllable has a final batchim consonant, that consonant moves into the empty doorway to start the following vowel. The classic example is the word for music, written as 음악 (eum-ak). Instead of pronouncing two separated beats [eum] and [ak], native Korean speakers slide the final ㅁ into the empty slot of the second syllable, pronouncing it naturally as [eu-mak]. Similarly, the verb 먹어 (eat, from 먹 + 어) is pronounced as [meo-geo], and 걸어 (walk, from 걸 + 어) becomes [geo-reo]. This liaison process requires zero effort from your mouth because it follows the natural path of minimal resistance.
| Written Word | Literal Syllables | Actual Pronunciation | Meaning |
|---|---|---|---|
| 음악 | 음 + 악 | [으막] eum-ak -> eumak | music |
| 먹어 | 먹 + 어 | [머거] meok-eo -> meogeo | eat or eats |
| 걸어 | 걸 + 어 | [거러] geol-eo -> georeo | walk or walks |
| 집이 | 집 + 이 | [지비] jip-i -> jibi | the house (subject) |
| 물이 | 물 + 이 | [무리] mul-i -> muri | the water (subject) |
| 눈이 | 눈 + 이 | [누니] nun-i -> nuni | the eyes / snow (subject) |
Exceptions and Special Cases
While most consonants link across directly as their true sounds (ㄱ becomes g, ㅂ becomes b, ㄹ becomes tapped r), a few letters undergo special transformations. For instance, when the letter ㅎ meets an initial vowel, it is often silenced entirely; the word 좋아 (good) is pronounced as [jo-a], not [jo-ha]. When double batchim meets a vowel, as you learned in the previous lesson, only the second consonant links across: 앉아 (sit) is pronounced as [an-ja], while the first consonant ㄴ stays rooted in the initial syllable. Recognizing these linking habits will instantly improve both your listening comprehension and spoken fluidity.
Practical Rules for Natural Reading
- Whenever you see a syllable ending in batchim followed by ㅇ, imagine shifting the consonant over.
- Batchim ㄹ always turns into a light tapped r sound when it links into a following vowel.
- Unreleased stops (ㄱ, ㄷ, ㅂ) soften into natural voiced consonants (g, d, b) when linking.
- Do not pause or place a glottal stop between syllables in a single word.
- Practice reading Korean text aloud in continuous phrases rather than isolated syllable blocks.
