Understanding Irregular Korean Verbs: The Key to Fluid Korean Speech
Learning Korean can be an exciting journey, but encountering irregular Korean verbs for the first time can feel overwhelming. Unlike regular verbs that follow consistent conjugation patterns, irregular verbs change their stems in certain situations, creating exceptions to the rules you’ve diligently memorized.
The good news? These irregularities actually follow predictable patterns. Once you understand these patterns, you’ll find that Korean verb conjugation becomes much more intuitive. Many students wonder how many irregular verbs in Korean they need to learn. While the exact number varies depending on ho
Why Irregular Verbs Matter
Mastering irregular Korean verbs is crucial because they include some of the most commonly used verbs in everyday Korean conversation. Verbs like 듣다 (to hear/listen), 춥다 (to be cold), and 아름답다 (to be beautiful) all follow irregular patterns. An irregular Korean verbs list typically includes these common patterns: ㅂ, ㄹ, ㅅ, 르, ㄷ, 으, and ㅎ irregulars.

The Main Types of Irregular Korean Verbs
- Without proper knowledge of these irregularities, you might find yourself making frequent grammatical errors that could affect how clearly you communicate. Let’s break down the most common types of irregulars you’ll encounter in your Korean language learning journey:
ㅂ (bieup) Irregular Verbs
This is one of the most common irregular patterns. Verbs ending with ㅂ transform when followed by a vowel.
For example:
- 춥다 (to be cold): 추워요 (it’s cold)
- 덥다 (to be hot): 더워요 (it’s hot)
- 맵다 (to be spicy): 매워요 (it’s spicy)
The ㅂ changes to 우 or 오 depending on the vowel harmony.
Example
Original Korean Sentence
날씨가 너무 추워요.
Pronunciation Guide
날씨가 (nal-ssi-ga) 너무 (neo-mu) 추워요 (chu-wo-yo).
Meaning and Context
날씨 (weather) 가 (subject marker) 너무 (too much) 춥 (to be cold) * 어요 (is; I’m telling you polite and friendly).”
Pronunciation Patterns for Conjugations
⊳ 춥 + 어요 = 추워요. The ㅂ changes to 우 when followed by a vowel.
⊳ But I teach it this way: 춥 + 어요 = 추워요. Rapidly pronouncing ‘춥’ and ‘어’ results in ‘추워’.
English Translation
The weather is very cold.
Literal Translation
Weather is too cold.
ㄹ (rieul) Irregular Verbs
Verbs ending with ㄹ often drop this final consonant when certain endings are attached.
For example:
- 알다 (to know): 아는 (knowing)
- 살다 (to live): 사는 (living)
- 팔다 (to sell): 파는 (selling)
Example
Original Korean Sentence
서울에 사는 사람들은 바빠요.
Pronunciation Guide
서우레 (seo-u-re) 사는 (sa-neun) 사람드른 (sa-ram-deu-reun) 바빠요 (ba-ppa-yo).
Meaning and Context
서울 (Seoul) 에 (in) 살 (to live) * 는 (present participle) 사람 (person) 들 (plural) 은 (topic marker) 바쁘 (to be busy) * 어요 (are; I’m telling you polite and friendly).”
Pronunciation Patterns for Conjugations
⊳ 살 + 는 = 사는. The ㄹ is dropped when followed by 는.
⊳ But I teach it this way: 살 + 는 = 사는. Rapidly pronouncing ‘살’ and ‘는’ results in ‘사는’ to make it easier.
Grammar
* 는: people (who) live
English Translation
People who live in Seoul are busy.

르 (reu) Irregular Verbs
These verbs undergo a transformation where 르 changes to ㄹ라/ㄹ러.
