In this lesson, we’ll cover everything you need to know about Korean conjugation.
We’ll explain what Korean conjugation is, how to use it, and when to use it.
Let’s go over some common Korean conjugations – and rules related to them – so that you can get kickstarted on creating your own conjugated sentences!

What is Korean conjugation?
Korean conjugations in Korean grammar determine the meaning, tense, tone, and mood of sentences. It’s important to learn conjugation as you progress in learning Korean.
For example, let’s say you’re going to use the verb “go” in a sentence. The base form is in Korean is:
Base Form: 가다 (gada) – to go
However, you need to change it to the present tense.
Conjugated Korean verb: 저는 가요 (I go)
We’ve added 저는 (“I”) as the subject, and then conjugated 가다 (to go).
However, unlike in any other language, Korean grammar takes conjugation to another level. Conjugations in Korean aren’t limited to Korean verbs. Other parts of speech such as adjectives can be conjugated.
Korean Verb and Adjective Conjugation
Korean verb and adjective conjugations are almost the same. Most of the conjugation rules for Korean verbs also apply to adjectives. Once you learn the Korean verb conjugation rules, it’ll be easy to conjugate adjectives.
How many conjugations are there in Korean?
There are 40 basic verb endings, but there are over 400 verb endings when all are combined. They are made up of different Korean grammar categories, such as the different tenses (past, present, and future tense), honorifics, and voices, to name a few.
Korean Verb Conjugation
Common Korean verb conjugations can be classified into two: verb endings and tenses. There are nine Korean verb endings and three verb tenses you can start learning.
These verb conjugations will allow you to build your own sentences and express yourself.
For example, if you want to say you’re not good at something, you’ll use the verb ending ~지 못 해요 (~ji mot haeyo).
If you want to tell your friend of your plan tomorrow or on the coming weekend, you’ll use the future tense verb conjugation.
Korean verb endings
These are a few of the common Korean verb endings you can use for verb conjugation.
- 입니다 (imnida), 이에요(ieyo) or 예요 (yeyo)– Is, am, are
- 있다 (itda ) – To have, To exist and
- 없다 (eopda )– Not to have, To not exist
- ~지 않아요 (~ji anayo) – Don’t
- ~지 않았어요 (~ji anasseoyo) – Didn’t
- ~지 않을 거예요 (~ji aneul geoyeyo) – Won’t
- ~지 못 해요 (~ji mot haeyo) –Can’t
- ~지 했어요 (~ji haesseoyo) – Couldn’t
- ~지 할 거예요 (~ji hal geoyeyo)– Won’t be able to
Korean Present Tense
Similar to English, Korean verbs have present tense. When expressing Korean verbs in the present, the Korean verb conjugations used are 아요 (ayo) or 어요 (eoyo) and ㅂ니다 (bnida) or 습니다 (seumnida).
Korean Past Tense
Korean verbs are also expressed in the past tense. When expressing Korean verbs in the past, the Korean verb conjugation used is the 았어요 (asseoyo) and 었어요 (eosseoyo).
Korean Future Tense
The Korean verb conjugation used for future tense is the 겠어요 (gesseoyo) and (으)ㄹ 거예요 (eul geoyeyo).

Korean verb conjugation can be a bit tough to learn when you’re just beginning to learn Korean. It’ll become easier as you progress by learning more Korean verb endings and practicing using them more often. Soon, you’ll be able to master Korean verb conjugation!
How does Korean Verb Conjugation work?
Korean verb conjugation is pretty easy to do. All you need to do is to drop the 다 verb endings from the verb stem and then add the appropriate verb endings. The correct verb endings to be used when conjugating verbs are determined by the final or last vowel after dropping the 다 verb endings from the verb stem.
We’ll get more into the details of conjugations in Korean in a while.
What’s the common Korean verb conjugation?
The common Korean verb conjugation is the use of 아요 (ayo) and 어요 (eoyo) which gives the Korean verb its polite and present tense form.
Let’s use the Korean verbs 자다 (jada) and 먹다 (meokda) as an example. These 2 Korean verbs are both in their verb stem form.
As mentioned earlier, verb conjugations in Korean happen by dropping the 다 verb endings from the verb stem.
For the Korean verbs 자다 and 먹다, we’ll need to drop the 다 verb endings which will make them:
자다 → 자
먹다 → 먹
If the final or last vowel after dropping 다 is either ㅏ or ㅗ, you’ll use 아요. But if the final or last vowel after dropping 다 is ㅓ, ㅣ, or ㅜ, you’ll use 어요. So for the two examples of Korean verbs above, they’ll become
자 → 자요 (jayo)
먹 → 먹어요 (meogeoyo)
How important is it to learn Korean Conjugation?
When learning the Korean language, particularly Korean grammar, Korean verb conjugation is very important to learn. As mentioned earlier, it sets the tense, tone, and meaning of your sentences which are basically all essential elements you’ll need when communicating.
Koreans give emphasis to politeness in everything including their language. Korean verb conjugation will help you show your respect and politeness towards a person.
Once you get familiar with the different conjugations, it’ll be easy for you to convey and appear to be respectful and polite.
Which part of the verb do you conjugate?
Before learning which part of the Korean verb we need to conjugate, we need to take note that each Korean verb, adverb, and adjective consist of two pieces: a stem and an ending. The first part is the stem, and 다 is the ending. These are usually their dictionary form.
When you conjugate any word, you will drop the 다 and replace it with the conjugation. Whenever you conjugate a verb, you only need to think of your tense and tone. The conjugation doesn’t change for the first person, second person, multiple people, etc.
Let’s take a quick look at some common Korean verbs in their basic form or dictionary form!
These Korean verbs are made up of a verb stem and a 다 ending.
How to make the conjugation form of the verbs
In addition to what we already know about how we conjugate verbs in Korean, many conjugations come together with a small puzzle piece that connects the stem to the conjugation in the most natural way. Let’s look at some simple examples of this.
말하다 + -아/어 → 말해요 (malhaeyo)
만나다 + -아/어 → 만나요 (mannayo)
닫다 + -아/어 → 닫아요 (dadayo)
가르치다 + -아/어 → 가르쳐요 (gareuchyeoyo)
As you can see, the puzzle piece slightly changes the verb stem it joins. Most of the time the Korean verbs play nice with them, so the rules are easy to learn.
How do I combine the verb stem and conjugation?
Simply, when 아 meets 아, it drops out. And when 아 meets 오, they connect together into one syllable; for example, 보 becomes 봐. When the verb stem ends in a consonant after 아 or 오, 아 becomes its own syllable.
For all other verb stems, you connect them with 어. When the verb stem ends with 이 the 이 + 어 combination cooks up 여. Only the verb 하다 is different and turns into 해.
Some conjugations also require the puzzle piece 으 to be connected when a verb stems ends with a consonant. (으)면, which we will introduce below, is one such conjugation. We’ll go over how to conjugate irregular verbs at a later time.
Common Korean conjugations
In this part of the lesson, we’ll be showing the different conjugations for 2 of the commonly used Korean verbs 보다 (boda) and 만들다 (mandeulda).
보다 (boda) and 만들다 (mandeulda) are the dictionary form of the Korean verbs “to watch or to see” and “to make.” Both Korean verbs are made up of a verb stem and a 다 (da) ending.
Notice that the Korean verbs 보다 (boda) and 만들다 (mandeulda) have different last letters when 다 (da) is dropped. 보다 (boda) ends in a vowel while 만들다 (mandeulda) ends in a consonant.

하다 (hada) Conjugation
The verb 하다 (hada) generally means “to do” in English. It is usually attached to words to make them either action verbs or descriptive verbs. For example:
공부 (gongbu | study) + 하다 (hada | to do)= 공부하다 (gongbuhada | to study)
요리 (yori | cook)+ 하다 (hada | to do) = 요리하다 (yorihada | to cook)
Below are the conjugation examples of the verb 하다 (hada):
- 하다 (hada) = standard form
- 해요 (haeyo) = polite/formal ending verb for a noun that ends in a vowel or consonant, present
- 했어요 (haesseoyo) = polite/formal ending verb for nouns ending in a vowel or consonant, past*
- 했었어요 (haesseosseoyo) = polite/formal ending verb for nouns ending in a vowel or consonant, past perfect*
이다 (ida) Conjugation
The verb 이다 (ida) is the Korean equivalent of “to be” in English. It is usually used to identify people and objects. When using it to form sentences, it can be used with the following sentence structure:
Subject and particle + Noun입니다
Here are conjugation examples for the verb 이다 (ida) – to be.
- 입니다 (imnida) = honorific verb, present tense
- 입니까 (imnikka) = honorific question verb, present
- 이에요 (ieyo) = polite/formal ending verb for nouns ending in a consonant, present
- 예요 (yeyo) = polite/formal ending verb for that nouns ends in a vowel, present
- 이었어요 (ieosseoyo) = polite/formal ending verb for nouns ending in a consonant, past*
- 였어요 (yeosseoyo) = polite/formal ending verb for nouns ending in a vowel, past*
- 야 (ya) = casual/informal ending verb for nouns ending in a vowel, present
- 이야 (iya) = casual/informal ending verb for nouns ending in a consonant, present
*Note: if you wish to use the past tense for 이다 (ida) on a casual level, use this form and simply drop the 요 (yo) from its tail
You may be thinking, “that’s quite a bit of vocabulary to remember!”
It gets easier with practice, and this grammar rule allows sentences to be more specific. Read these example sentences for 이다 (ida) to see:
I am Joana
How old are you?
I am a Vietnamese.
I am a singer.
He was a soldier.
He was a good friend.
I am a man.
I am a student
Let’s take a closer look at the verb, 있다 (itda) – to have. Here are its basic conjugations in Korean grammar:
- 있습니다 (itseumnida) = honorific verb, present
- 있습니까? (itseumnikka) = honorific verb, present
- 있었습니다 (isseotseumnida) = honorific verb, past
- 있어요 (isseoyo) = polite/formal verb, present*
- 있었어요 (isseosseoyo) = polite/formal verb, past*
*Note: To create the casual/informal form, simply use these without the 요 (yo) at the end
You’ll notice that 있다 (itda) conjugate verbs much like 이다 (ida), with only slight changes in the letters because of the word itself.
있다 operates more like an adjective than a verb, changing how it works with particles. Hopefully, these examples will help illustrate that:
I have a question.
Do you have a question?
I had a girlfriend.
I have a little brother.
I have a bag.
I had a boyfriend.
I had an appointment.
없다 (eopda) Conjugation
Next, 없다 (eopda) means “to not have.” It is the opposite of 있다(itda) which means “to have.” It is conjugated the same as 있다 (itda). Here are some grammar examples:
I don’t have a big sister.
I don’t have a car.
I didn’t have time.
I don’t have cash.

What about the future tense in the to be section. Can you see if you can get the formal, informal, and casual
Thank you for the suggestion. 이다’s future tense is 일 것이다 and in speech form they are 일 겁니다(formal), 일 거예요(standard), 일 거야(casual).
Also in the Korean verb endings section, the lists of endings for present tense, past tense and future tense are incomplete (not specifying the informal, formal and polite endings), compared to the actual verb conjugation examples later on. I think it would help to have the same information in both sections to make it less confusing.
Thanks for your suggestions, Ana! I’ll talk to the team about updating the article. ^^
Typo: in the Korean verb endings section there is an unfinished second sentence (You ca)
Thanks for your correction, Ana! We will correct it soon. ^^
I am just starting to learning Korean and have a question on conjugation. I have a basic rules down on how to conjugate. You drop the 더 and depending on the last consonant or vowel you add the proper ending. But what does for example 가요 mean? Like is it I go? She goes? And depending on the subject or topic do I have to add a different ending?
Hi, Livie! “가요” usually means “Let’s go” if no subject was attached. ^^
Thank you for replying. How do I add a subject? Do you have a lesson on adding subjects to a verb or adjective?
나는 (I+subject marking particle – informal) 가요
So this would be I go.
That’s correct. 나는 가요 means “I go.”
annyeong, i would like to learn more in Korean Language and correct pronunciation of it. Any recommendation? Gamsahabnida!
