Korean Double Batchim ㄺ: Sounds, Rules and Examples

The Korean double batchim ㄺ is the pair ㄹ + ㄱ at the bottom of a syllable, as in 닭 (chicken) and 읽다 (to read). It is a right-letter pair: alone or before most consonants it is said [ㄱ], so 닭 is [닥]. This lesson adds the one exception, 읽고 [일꼬], and the vowel forms such as 읽어요 [일거요].

What you'll learn

• Say 닭 [닥], 읽다 [익따] and 맑다 [막따] with a single [ㄱ].
• Apply the exception in 읽고 [일꼬] and 맑게 [말께], and explain why 닭고기 is still [닥꼬기].
• Pronounce both letters in 읽어요 [일거요] and 닭이 [달기].
• Predict the [ㅇ] in 읽는 [잉는] and 닭만 [당만].

Prerequisites: Double Batchim Rules, especially the idea that ㄺ, ㄻ and ㄿ keep the right letter. Estimated time: 30 minutes.

What Is the Korean Double Batchim ㄺ?

The Korean double batchim ㄺ is a final consonant cluster made of ㄹ (rieul) on the left and ㄱ (giyeok) on the right. Korean grammars call it 리을기역 받침 or simply ㄺ 받침. Like every double batchim, it can be heard in full only when a vowel follows; in every other position one letter goes silent.

ㄺ is one of only three right-letter pairs. In the double batchim rules, eight pairs keep the left letter and three, ㄺ, ㄻ and ㄿ, keep the right one. For ㄺ that means the ㄹ is silent and you say [ㄱ].

The source for every form on this page is the Standard Pronunciation Rules (표준 발음법) of the National Institute of Korean Language (국립국어원): Article 11 for the basic rule and its exception, Article 14 for vowels, Article 18 for the change before ㄴ and ㅁ, and Article 23 for tensification.

Knowing the rule is the easy part. The next section explains why ㄺ trips up so many learners anyway.

Why English Speakers Struggle with ㄺ

English speakers struggle with ㄺ because English says "lk" clusters in full, as in "milk" and "silk". The natural move is to read 닭 as "dalk", with both sounds. Korean allows only one final consonant sound, so a Korean listener hears "dalk" as foreign or as an extra syllable.

The second difficulty is that learners usually meet ㄺ after the left-letter pairs. Having learned 값 [갑] and 앉다 [안따], they apply "say the left letter" and produce 닭 as [달]. That is the opposite of the standard form. A third difficulty is that ㄺ has an exception inside verbs, so even learners who know "right letter" hear 읽고 as [일꼬] and wonder whether the rule is wrong.

The solution is to learn ㄺ in three settings: alone, before ㄱ in a verb, and before a vowel. The next section starts with the simplest setting.

How Is ㄺ Pronounced at the End of a Word?

At the end of a word, ㄺ is pronounced [ㄱ]: the ㄹ is silent. Close the back of your tongue against the soft palate and hold it without a puff of air, exactly as you would for 국 or 박.

The same [ㄱ] appears before most consonants. 읽다 (to read) is [익따], 맑다 (to be clear) is [막따] and 늙지 (old, as in "isn't old") is [늑찌]. Notice that the consonant after [ㄱ] becomes tense: ㄷ turns into [ㄸ] and ㅈ into [ㅉ]. This is regular tensification, the same change that makes 학교 sound like [학꾜].

Why Do 읽다 and 익다 Sound the Same?

읽다 (to read) and 익다 (to ripen, to be cooked) sound the same in the dictionary form, because both end in [ㄱ] before ㄷ: each is [익따]. The difference appears only when a vowel ending follows. 읽어요 is [일거요], with the ㄹ restored, while 익어요 is [이거요], with no ㄹ at all.

This pair is a useful listening test. If you hear [익따] alone, context tells you which verb it is. If you hear [일거요], it can only be 읽어요. Korean spelling keeps the silent ㄹ in 읽다 precisely because it comes back in forms like these.

ㄺ before ㅎ: 밝히다 and 읽히다

When ㅎ follows ㄺ, the ㄹ is kept and the ㄱ merges with ㅎ into an aspirated [ㅋ]. Article 12 of the Standard Pronunciation Rules gives 밝히다 (to light up, to reveal) as [발키다]. The same pattern appears in 읽히다 (to be read, to make someone read) [일키다] and 긁히다 (to get scratched) [글키다]. These forms are less common at beginner level, but they show that both letters of ㄺ survive whenever the next sound can carry one of them.

So far ㄺ behaves mostly like a plain ㄱ batchim. The next section shows the one place where it does not.

When Does ㄺ Sound Like ㄹ?

ㄺ sounds like [ㄹ] in one situation only: when a verb or adjective stem ends in ㄺ and the next ending starts with ㄱ. Article 11 of the Standard Pronunciation Rules states this exception directly, with the examples 맑게 [말께], 묽고 [물꼬] and 얽거나 [얼꺼나].

Two details make this exception easier to apply. First, the ㄱ of the ending is still tense, so the result is [일꼬], not [일고]. Second, the exception is limited to verb and adjective stems. Nouns keep [ㄱ] before ㄱ: 닭고기 (chicken meat) is [닥꼬기] and 흙과 (with soil) is [흑꽈].

One way to remember the exception: saying [익꼬] would put two back-of-tongue sounds side by side, and keeping ㄹ makes the ending stand out. Treat that as a memory aid, not as the official reason. The rule itself simply lists the case.

The exception matters most in verb conjugation, where the same stem meets many different endings.

How Does 읽다 Change in Conjugation?

읽다 changes its pronunciation with every ending, because each ending puts a different sound after ㄺ. The table below shows ten common forms of 읽- (read) with their spoken forms.

The 읽는 row needs one more step. ㄺ first reduces to [ㄱ], then [ㄱ] becomes [ㅇ] because ㄴ follows. This change is called Korean nasalization (비음화), and it also turns 닭만 into [당만] and 맑네 into [망네]. For a single, everyday form with a full audio walkthrough, see how to pronounce 읽어요.

Rows with a vowel ending all look alike: both letters come back. The next section explains that pattern in detail.

How Is ㄺ Pronounced before a Vowel?

Before a vowel ending or particle, ㄺ is pronounced with both letters: the ㄹ closes the first syllable and the ㄱ moves to the start of the next one. Article 14 of the Standard Pronunciation Rules describes this movement, called liaison (연음).

Here the ㄱ is plain, not tense, because it now starts a syllable after ㄹ, which does not trigger tensification. It often sounds close to an English g: [달기] is roughly "dal-gi". There is one limit. If the next part is a separate word rather than a particle, only [ㄱ] links: 닭 앞에 (in front of the chicken) is [다가페]. More pairs and drills are in the lesson on double batchim before a vowel.

You now have all three settings. The worked example puts them together in one noun.

Worked Example: 닭 in Four Forms

Follow 닭 (chicken) through four forms. For each one, ask what comes next, then choose the setting.

1. 닭 alone. Nothing follows, so one letter is said. ㄺ is a right-letter pair: keep ㄱ. Say [닥].
2. 닭이 (subject). The particle 이 starts with a vowel. Keep ㄹ in the first syllable and move ㄱ to the second. Say [달기].
3. 닭고기 (chicken meat). ㄱ follows, but 닭 is a noun, so the verb exception does not apply. Keep [ㄱ], and make the next ㄱ tense. Say [닥꼬기].
4. 닭만 (only chicken). ㅁ follows. Reduce to [ㄱ], then nasalize it to [ㅇ]. Say [당만].

You'll know you have it when 닭 sounds the same as 닥, 닭이 has a light ㄹ that flows into 기, and 닭만 rhymes with 당만. Now try the same four questions with 읽다 and notice that step 3 changes: 읽고 is [일꼬], because 읽- is a verb stem.

Common Mistakes with ㄺ

Mistake 1: saying the left letter. Learners often assume ㄺ follows the "left letter" default, so they say 닭 as [달]. Actually ㄺ is one of the three right-letter pairs: [닥]. Fix: link ㄺ to 닭 and say "닭, 닥" five times.

Mistake 2: saying both letters before a consonant. Learners often say 읽다 as "ilk-da". Actually only one letter is allowed, and the ㄷ is tense: [익따].

Mistake 3: extending the exception to nouns. Learners who have just learned 읽고 [일꼬] often say 닭고기 as [달꼬기]. Actually the exception is limited to verb and adjective stems, so the noun keeps [ㄱ]: [닥꼬기].

Mistake 4: forgetting nasalization. Learners often say 읽는 as [익는]. Actually [ㄱ] before ㄴ becomes [ㅇ]: [잉는]. This is the same change as 국물 [궁물].

Mistake 5: dropping a letter before a vowel. Learners often say 읽어요 as [이거요] or 닭이 as [다기]. The standard forms are [일거요] and [달기]. Casual Seoul speech sometimes drops the ㄹ in 닭이, but learn the standard form first.

These mistakes share one cause: not checking what follows ㄺ. The practice set below asks you to make that check every time.

Practice: Korean Double Batchim ㄺ

Exercise 1. Write the spoken form.

1. 흙
2. 맑다
3. 늙지
4. 까닭

Exercise 2. Is ㄺ said [ㄱ] or [ㄹ] here? Write the spoken form.

1. 밝고
2. 밝다
3. 닭고기
4. 긁게

Exercise 3. Write the spoken form. Watch for vowels and for ㄴ.

1. 닭을
2. 맑은
3. 읽는
4. 흙만

Answers.

Exercise 1: 1 [흑], 2 [막따], 3 [늑찌], 4 [까닥].

Exercise 2: 1 [ㄹ], [발꼬]. 2 [ㄱ], [박따]. 3 [ㄱ], because 닭 is a noun: [닥꼬기]. 4 [ㄹ], [글께].

Exercise 3: 1 [달글]. 2 [말근]. 3 [잉는]. 4 [흥만].

If Exercise 2 caused problems, reread the exception table and say each pair of forms aloud, for example 밝고 [발꼬] and 밝다 [박따].

Where to Go Next

The next lesson, Korean double batchim ㄻ, covers the second right-letter pair, as in 삶 [삼] and 젊다 [점따]. ㄻ has no ㄱ exception, so it is simpler than ㄺ. The full list of pair lessons is in Double Batchim.

This lesson does not cover regional speech. In parts of the southeast, many speakers say 닭 closer to [달]. You will hear these forms in dramas and from friends, and they are not errors in those dialects. The standard Seoul forms taught here are the ones to use in exams and formal speech.

In short, the Korean double batchim ㄺ is said [ㄱ] alone and before most consonants, [ㄹ] before ㄱ in verb and adjective stems, and with both letters before a vowel ending.

Frequently Asked Questions

How do I say 읽어요? Say [일거요]. 읽어요 adds the vowel ending 어요 to the stem 읽-, so both letters of ㄺ are heard: ㄹ stays in the first syllable and ㄱ moves to the second. Do not drop the ㄹ ([이거요]) or the ㄱ ([이러요]). Revised Romanization writes it ilgeoyo, which matches the spoken form.

Why is 읽고 [일꼬]? 읽고 is [일꼬] because the Standard Pronunciation Rules, Article 11, make one exception to the right-letter rule: when a verb or adjective stem ends in ㄺ and the ending starts with ㄱ, the ㄹ is kept instead. The following ㄱ is still tense, so you hear [꼬]. Compare 읽다 [익따], where the ending starts with ㄷ.

Is 닭 pronounced 닥 or 달? In standard Korean, 닭 is pronounced [닥]. ㄺ keeps its right letter, ㄱ, at the end of a word. Some regional speakers, especially in the southeast, say something closer to [달], and you may hear it in dramas, but [닥] is the standard form and the one taught in textbooks.

Which words end in ㄺ? The nouns are few: 닭 (chicken), 흙 (soil), 칡 (arrowroot) and 까닭 (reason). The verbs and adjectives are more useful: 읽다 (read), 맑다 (clear), 밝다 (bright), 늙다 (old), 긁다 (scratch), 붉다 (red), 묽다 (watery) and 굵다 (thick). All of them follow the same rules on this page.

Does 맑게 follow the same rule as 읽고? Yes. 맑다 (clear) is an adjective whose stem ends in ㄺ, and the adverb ending 게 starts with ㄱ, so the ㄹ is kept: 맑게 [말께]. The same happens in 밝게 [발께] and 늙고 [늘꼬]. Before other consonants these stems return to [ㄱ]: 맑다 [막따], 맑지 [막찌].
