Korean Ng Sound: Sounds, Rules and Examples

The Korean ng sound is the final ㅇ, pronounced like the "ng" in English "sing" without a hard g after it. At the start of a syllable, the same letter ㅇ is silent. So 강 (river) ends in ng, while 아 starts with no consonant at all. This lesson trains both jobs of ㅇ with audio.

What you'll learn

• Pronounce 강, 방, 공 and 사랑 with a clean ng and no extra g.
• Tell the silent ㅇ in 아 from the ng sound in 앙.
• Keep final ㅇ apart from ㄴ and ㅁ in 간, 감 and 강.
• Explain why 사랑이 is spoken [사랑이].

Prerequisite: none beyond reading Hangul blocks. The letter itself is introduced in Korean consonants. Estimated time: 25 minutes.

What Is the Korean Ng Sound?

The Korean ng sound is a nasal consonant made with the back of the tongue. The tongue rises to touch the soft palate (the soft part at the back of the roof of the mouth), the mouth stays open, and the voice flows through the nose. Linguists call it a velar nasal ("velar" refers to the velum, another name for the soft palate).

Korean writes this sound with ㅇ, but only when ㅇ is the last consonant of a block. The words below all end in the ng sound.

English speakers already know this sound, which makes the lesson shorter than it first looks. What causes trouble is how English uses it.

Why English Speakers Add a G or an N

English speakers add a g or an n because English uses ng in a different way. The ng in "sing" and "singer" is the same nasal as the Korean one. But the ng in "finger" is followed by a hard g, and the ng of "singing" is often relaxed into "singin'" with an n. Learners carry these habits into Korean, in two forms:

• Adding a g. A learner says 강 as "gang-guh" or 사랑 as "sa-rang-g". The extra release at the end turns one syllable into a syllable plus a burst.
• Swapping for n. A learner says 강 as [간], because the tongue tip is the easiest closure to reach. Korean listeners hear a different word.

A third difficulty is listening. Korean final nasals are usually unreleased, so the sound ends without a burst or a trailing vowel. The difference between ㄴ, ㅁ and ㅇ then lies mostly in the closure and in how the vowel bends toward it. Learners trained on English, where final consonants often have a release, can miss that clue. The cure is the memory anchor in the next section.

How Do You Make the Final ㅇ Sound?

You make the final ㅇ sound by saying "sing", not "singer", and stopping after the ng. A four-step drill builds the position.

1. Say "singer" slowly. Notice that the middle sound is ng and that no g follows it: s-i-ng-er.
2. Stop after "sing". Hold the back of the tongue against the soft palate. The voice keeps going through the nose.
3. Add a Korean vowel in front. Hold the same closure and say 강: the vowel ㅏ first, then the held ng.
4. End without a release. Do not drop the tongue with a burst of air. Let the sound fade while the closure holds.

The memory phrase is "singer, not finger". Singer has the clean ng, finger has ng + g. A Korean ㅇ follows "singer".

You can check the position by feeling for the nose. Pinch your nostrils closed while you hold the ng: the sound should stop, because nasal sounds need the nose. If the sound continues, the air is escaping through the mouth, so the back of the tongue is not fully closed. The next question is the opposite one: what happens when ㅇ comes first?

Is ㅇ Silent at the Start of a Syllable?

Yes, ㅇ is silent at the start of a syllable. In Hangul, every block needs a consonant slot at the top left, so ㅇ fills the slot when a syllable starts with a vowel. This role is called a placeholder consonant, and the letter makes no sound there. The syllable 아 is just the vowel ㅏ.

The pairs below put the silent ㅇ and the ng sound side by side.

The ㅇ in the left column is the same letter as the ㅇ in the right column, but it plays two different roles. A good rule is to look at where ㅇ sits in the block: top means silent, bottom means ng.

Does the ng sound ever start a word? In Standard Korean, no. Fifteenth-century Hangul had a separate letter, ㆁ (yet-ieung), for the ng sound, which could then also begin a syllable in some words. It later merged with ㅇ in writing and is no longer used. You can read about it in obsolete Hangul letters. Since no word starts with ng, you do not need to practise it. What you do need is to keep ㅇ apart from its two close neighbours.

How Is Final ㅇ Different from ㄴ and ㅁ?

Final ㅇ differs from ㄴ and ㅁ in where the mouth closes. All three are nasals, so the voice goes through the nose, but the closure moves.

Practise by saying each set as a slow triple: 간, 감, 강. Your tongue tip lifts for 간, your lips close for 감, and your mouth stays open with the tongue tip down for 강. A fourth check is to watch a mirror: only 감 closes the lips. More ear training with these sounds is in nasal and liquid minimal pairs. The three nasals also behave differently in a sentence, which is the next question.

Does ㅇ Link to the Next Vowel?

No, ㅇ does not link to the next vowel. In Korean, a final consonant usually moves to the empty slot of a following vowel syllable, a process called liaison. Final ㅇ is the exception, because no Korean syllable can begin with ng. The ng sound stays where it is.

This is a useful listening cue. If you hear the syllable 이 pronounced on its own after a nasal, the word probably ends in ㅇ. If the nasal and the vowel have blended into one syllable, as in [사니], the word ends in ㄴ or ㅁ. The full liaison rule is in Korean liaison, and the final ㅇ itself has a short lesson in the ㅇ batchim. The ng sound also turns up in places where ㅇ is not written.

Where Else Does the Ng Sound Appear?

The ng sound also appears where the spelling shows ㄱ. When ㄱ comes before ㄴ or ㅁ, the nasalization rule changes it to ng. So 학년 (school year) is spoken [항년], 먹는 (eating) is [멍는] and 국물 (soup) is [궁물]. Revised Romanization records this: 학년 is hangnyeon.

This means learners meet the ng sound more often than the letter ㅇ suggests. The lesson on Korean ㄱ nasalization explains the rule in full. Short sentences come next, and then the full steps for one word.

Hearing the Ng Sound in Short Sentences

Short sentences train the sound in a natural rhythm, where the ng is followed by another word. In each one, the ng is unreleased and flows straight into the next word.

• 한강에 가요. (I go to the Han River.) Spoken: [한강에 가요]
• 방이 커요. (The room is big.) Spoken: [방이 커요]
• 사랑해요. (I love you.) Spoken: [사랑해요]

In 한강에, the first ㄴ is a tongue-tip nasal and the second nasal is the ng: two different closures in one word. In 방이, the ng stays in 방 and 이 is a separate syllable, as the liaison table showed. A fair limit applies to all of this: the audio models one standard Seoul pronunciation, and casual speech may soften the closure at the end of a syllable. Start with the careful form, and the softer forms will be easy to follow later.

Worked Example: Saying 강

Follow these steps to say 강 (river).

1. Start with ㄱ. Press the back of the tongue to the soft palate and release with a plain k-g sound, with little puff.
2. Say the vowel ㅏ. Open the mouth as in "father".
3. Close at the back. Raise the back of the tongue to the soft palate again. The tongue tip stays down behind the lower teeth.
4. Let the voice go through the nose. Hold the ng for a short moment.
5. Stop without a burst. Do not release: [강].

You will know you have it when the word ends in a humming sound and not in a g. A test is to say 강 and 간 in a row: the tongue tip stays down for 강 and lifts for 간. Despite the clear steps, five slips come up again and again.

Common Mistakes with the Korean Ng Sound

Mistake 1: adding a g. Learners often assume 강 ends in "ng-g"; actually it ends in a clean ng, as in "singer". Fix: say "singer" and stop at "sing".

Mistake 2: turning ng into n. Learners sometimes say 강 as [간]; actually the tongue tip stays down and the back of the tongue closes. Fix: practise 간, 감 and 강 as a triple.

Mistake 3: saying ng at the start. Learners who have just met the sound say 아 as "nga"; actually initial ㅇ is silent. Fix: say the vowel alone.

Mistake 4: dropping the nasal. Learners sometimes say 강 as [가], with a nasalized vowel; actually the closure must be complete. Fix: touch the soft palate and hold.

Mistake 5: moving ng across. Learners often say 사랑이 as [사라니]; actually final ㅇ never moves, so it is [사랑이]. Fix: say 사랑, then the separate syllable 이.

All five mistakes come from treating ㅇ as one fixed sound. The practice set below separates its two jobs.

Practice: Say 10 Words with ㅇ

Exercise 1. Is the ㅇ silent or ng?

1. 아기
2. 강
3. 오이
4. 방
5. 사랑

Exercise 2. Write the spoken form.

1. 사랑이
2. 산이
3. 학년
4. 먹는

Exercise 3. Which word ends in the tongue-back closure: 간, 감 or 강?

Answers.

Exercise 1: 1 silent (아기: the ㅇ of 아 is at the top of its block). 2 ng. 3 silent (오이: both ㅇ are at the top of their blocks). 4 ng. 5 ng (사랑: the final ㅇ of 랑); the first block 사 has no ㅇ.

Exercise 2: 1 [사랑이]. 2 [사니]. 3 [항년]. 4 [멍는].

Exercise 3: 강.

If you missed more than one answer in Exercise 1, find the position of ㅇ in each block again: top means silent, bottom means ng. Then repeat the drill with "singer, not finger".

Where to Go Next

The next lesson, Korean F Sound, looks at another sound that has no direct Korean letter. The whole group of lessons is listed on the page for Difficult Korean Sounds.

This lesson does not cover the single ㄹ, the full nasalization rules or pitch. In short, the Korean ng sound is the held, unreleased nasal of "sing" written as ㅇ at the bottom of a block, and it never starts a syllable.

Frequently Asked Questions

Does ㅇ ever sound like ng at the start of a syllable? No. At the start of a syllable, ㅇ is silent and only holds the place of a consonant, so 아 is [아] and 이 is [이]. The ng sound appears only at the end of a syllable, as in 강 or 방. Standard Korean has no words that begin with ng.

Why is the final ㅇ hard for English speakers? English speakers hear ng mostly in words like "sing" and "finger", and they often add a g, as in "finger", or replace the sound with n. Korean needs ng with no g and no release. Practise the back-of-the-tongue closure with "sing" and hold it. Then add a vowel in front, as in 강.

Is ㅇ pronounced in 사랑이? Yes, the final ㅇ of 사랑 stays ng, and the word is [사랑이]. Korean does not move the ng sound onto the next vowel, because no syllable can begin with ng. Compare 산이, where the final ㄴ does move: [사니]. Apart from ㅎ, which falls silent before a vowel, final ㅇ is the only final consonant that does not move.

How do I say ng without a g? Say the word "singer" slowly and stop after "sing", holding the back of the tongue against the soft palate while the voice and the air go through the nose. That held sound is the Korean ng. Do not release the tongue with a burst, because the release is what makes a g.
