-(으)ㄴ/는 것 같다 Grammar in Korean: Meaning and How to Use It

What you'll learn

• Pick the right shape for present verbs (-는), past verbs (-(으)ㄴ), adjectives (-(으)ㄴ) and nouns (-인).
• Describe what you see or hear with 비가 오는 것 같아요 and 비가 온 것 같아요.
• Soften an opinion politely with 좋은 것 같아요.
• Tell apart a present or past impression from a guess about the future (-(으)ㄹ 것 같다).

Before you start: you should know how to find a stem (drop 다 from the dictionary form) and the polite ending -아요/어요. Audio plays only when you press a button.

What Does -(으)ㄴ/는 것 같다 Grammar Mean?

-(으)ㄴ/는 것 같다 grammar means "it seems that" or "it looks like." The speaker has a clue, such as a sight, a sound or a memory, and says what it points to. If you see a person on the phone with an angry face, you might say 화난 것 같아요, "He seems to be angry." You did not hear him say so.

The pattern has three parts. The first is a modifier, which is a form that lets a verb or adjective describe a noun: -는, -(으)ㄴ or 인. The second is 것, a dependent noun, which is a noun that cannot stand alone and always follows a describing word. The third is 같다, "to be like." So 오는 것 같다 is literally "it is like a thing that is coming." The modifier shows the time and the word class, and the rest stays the same. The time part is the key difference from -(으)ㄹ 것 같다, which looks to the future.

Here are the first two examples.

• 그 사람은 학생인 것 같아요. (geu sarameun haksaengin geot gatayo.) [그 사라믄 학쌩인걷까타요] = "That person seems to be a student."
• 비가 온 것 같아요. (biga on geot gatayo.) [비가 온걷까타요] = "It seems it rained."

Notice the sound. The 것 is pronounced [걷], and the ㄱ of 같 becomes tense, so you hear [걷까타요]. This follows the standard pronunciation rules (표준 발음법, Article 23) of the 국립국어원 (National Institute of Korean Language), which tense a plain consonant after a stop sound. The modifiers -는 and -(으)ㄴ do not cause tensing, so 온 것 is [온걷]. In everyday speech, 것 is often shortened to 거, as in 온 거 같아요. Next comes the mechanism that builds the pattern.

How Do You Form -(으)ㄴ/는 것 같다?

-(으)ㄴ/는 것 같다 is formed by choosing the right modifier for the word class and the time, then adding 것 같다. There are four main shapes. After a vowel, -ㄴ is added to the stem. After a consonant, -은 is added.

The table shows one idea: the modifier carries the time and the word class. The next three parts take the groups one at a time.

Stems Ending in a Vowel

A vowel stem takes -는 for a present verb and -ㄴ for a past verb or a present adjective. 가다 becomes 가는 (present) and 간 (past), and 크다 becomes 큰.

• 비가 오는 것 같아요. (biga oneun geot gatayo.) [비가 오는걷까타요] = "It seems it is raining." (You hear the rain.)
• 아이가 자는 것 같아요. (aiga janeun geot gatayo.) = "The child seems to be sleeping."
• 오늘은 많이 바쁜 것 같아요. (oneureun mani bappeun geot gatayo.) = "You seem very busy today."

Vowel stems are the simplest case. A stem with a final consonant needs a different sound.

Stems Ending in a Consonant

A consonant stem takes -는 for a present verb and -은 for a past verb or a present adjective. 먹다 becomes 먹는 (present) and 먹은 (past), and 많다 becomes 많은.

• 이 음식은 조금 매운 것 같아요. (i eumsigeun jogeum maeun geot gatayo.) [이 음시근 조금 매운걷까타요] = "This food seems a little spicy."
• 오늘은 사람이 많은 것 같아요. (oneureun sarami maneun geot gatayo.) [오느른 사라미 마는걷까타요] = "There seem to be many people today."
• 지금 밥을 먹는 것 같아요. (jigeum babeul meongneun geot gatayo.) [지금 바블 멍는걷까타요] = "He seems to be eating now."

The final consonant of 먹 meets the ㄴ of 는 and becomes ㅇ, so you hear [멍는]. In 많은, the ㅎ is silent, so you hear [마는]. Now for the stems that change shape.

Irregular Stems, past Adjectives and Nouns

Irregular stems change as usual before a vowel, and ㄹ stems drop the ㄹ before ㄴ:

• ㄹ stems: 살다 becomes 사는 (present) and 산 (past); 만들다 becomes 만드는 and 만든. 그 사람은 서울에 사는 것 같아요 ("He seems to live in Seoul").
• ㅂ-irregular adjectives: 춥다 becomes 추운, and 어렵다 becomes 어려운: 오늘은 날씨가 추운 것 같아요 ("It seems cold today"). A ㅂ verb like 돕다 becomes 도운 in the past.
• ㄷ-irregular verbs: 듣다 becomes 듣는 (present) and 들은 (past).
• 있다 and 없다 behave like verbs in the present: 있는 것 같아요, 없는 것 같아요. 그 사람은 지금 집에 없는 것 같아요 ("He doesn't seem to be home now").
• Past adjectives use 았/었던: 어제는 날씨가 추웠던 것 같아요 ("It seems the weather was cold yesterday").
• Nouns use 인 in the present and 이었던 or 였던 in the past: 학생이었던 것 같아요.

The sound of 추웠던 is [추웓떤], and 없는 is [엄는]. With the formation clear, one full sentence can be built step by step.

Worked Example: Building a Sentence with -(으)ㄴ/는 것 같다

-(으)ㄴ/는 것 같다 grammar turns a plain observation into an inference. Follow the steps with "It rained" when you see wet streets.

1. Start with the plain sentence. 비가 왔어요. (biga wasseoyo.) = "It rained." The predicate is 왔어요.
2. Find the dictionary form. 왔어요 comes from 오다 (to come, here "to fall"). The stem is 오.
3. Pick the shape. 오다 is a verb, and the event is in the past, so the modifier is -(으)ㄴ. The stem ends in a vowel, so add ㄴ: 오 becomes 온.
4. Add 것 같다. 온 + 것 같다 = 온 것 같다. Keep a space after 온 and after 것.
5. Choose the speech level. Result: 비가 온 것 같아요. (biga on geot gatayo.) = "It seems it rained."

You will know it worked when the subject (비가) stays in place and only the predicate changes from 왔어요 to 온 것 같아요. The most common slip at this step is picking the future shape (올) out of habit. If the rain has already happened, use 온. An impression can appear in several tenses and sentence types, and each has limits.

Which Tenses and Sentence Types Work with -(으)ㄴ/는 것 같다?

-(으)ㄴ/는 것 같다 works in statements and in questions, and in the present and past. The future uses a different modifier, -(으)ㄹ, and belongs to another pattern. The last word 같다 changes only for the speech level. The table shows the forms for 가다 and 크다 in the polite style.

The present statement and the question have the same shape. Rising tone turns 가는 것 같아요 into a yes/no question, and a question mark marks it in text. A question with a question word, such as 어디에 가는 것 같아요?, puts the stress on the question word and often falls or rise-falls at the end.

The negative can also be formed with 안: 안 가는 것 같아요 ("He seems not to go"), or by negating before 것: 가지 않는 것 같아요. Both are natural.

• 제가 열쇠를 잃어버린 것 같아요. (jega yeolsoereul ireobeorin geot gatayo.) = "I think I have lost my keys."
• 어제는 날씨가 추웠던 것 같아요. (eojeneun nalssiga chuwotdeon geot gatayo.) = "It seems the weather was cold yesterday."

The compatibility pattern is simple: the modifier shows both the time and the word class, and the speaker can include themselves. The most useful contrast for a learner is next to the pattern that looks ahead.

How Is -(으)ㄴ/는 것 같다 Different from -(으)ㄹ 것 같다 and -(으)ㄴ/는 모양이다?

-(으)ㄴ/는 것 같다 looks at the present or past, while -(으)ㄹ 것 같다 looks ahead or at an unseen state. -(으)ㄴ/는 모양이다 is a stronger inference from clear evidence. The point is time and strength.

The easy way to choose is to ask "when?" If it is already happening or finished, use the first. If it has not happened yet, use the second. Full rules for the future side are on the page for -(으)ㄹ 것 같다.

The third pattern, -(으)ㄴ/는 모양이다, uses the noun 모양 ("shape, appearance"). It sounds firmer, because the speaker points to clear evidence, such as a wet street and dripping umbrellas. 비가 온 모양이에요 is more like a conclusion than a hunch. Its own lesson is -(으)ㄴ/는 모양이다.

For firm future forms, Korean uses future guess -겠- or future tense -(으)ㄹ 거예요. Those pages cover them in full. Now for variations you will hear in real talk.

Variations and Edge Cases of -(으)ㄴ/는 것 같다

-(으)ㄴ/는 것 같다 has a few common variations. They show how flexible the pattern is in daily Korean.

• Softening an opinion. The pattern often replaces a direct statement. 이 노래가 좋은 것 같아요 can mean "I think this song is good," even though the speaker knows how they feel. It sounds modest and avoids pressure.
• Spoken 거 for 것. In speech, 것 shortens to 거: 오는 거 같아요. Keep 것 in careful writing.
• Modifying a noun. Change 같다 to 같은 to describe a thing: 비가 오는 것 같은 날씨 ("weather that looks like rain").
• With 아마 or 아무래도. The adverbs 아마 ("perhaps") and 아무래도 ("on balance") often come first and add to the uncertainty.
• Honorific -(으)시-. Place it before the modifier when the subject deserves respect: 선생님은 지금 바쁘신 것 같아요 ("The teacher seems busy now").

What Mistakes Do Learners Make with -(으)ㄴ/는 것 같다?

Learners most often pick the wrong modifier or the wrong time. Four slips come up again and again.

1. Using -(으)ㄹ 것 같다 for the past. 어제 비가 올 것 같아요 is wrong for "It seems it rained yesterday." Use 어제 비가 온 것 같아요.
2. Adding -는 to an adjective. 좋는 것 같아요 and 크는 것 같아요 are wrong for adjectives. Say 좋은 것 같아요 and 큰 것 같아요.
3. Confusing past and present. 간 것 같아요 means "He seems to have gone." 가는 것 같아요 means "He seems to be going." The modifier carries the time.
4. Forgetting to drop ㄹ. 살는 것 같아요 is wrong. Say 사는 것 같아요.

A quick check for any impression: Is the event present or past, not future? Is the word class right: verb, adjective or noun? Is the modifier right? If all three answers are yes, the sentence is sound.

The practice set below tests these points directly.

Practice and Answers

Try the items before you read the answer key.

1. Build the form. Write the polite present form of 먹다 ("to eat") with -(으)ㄴ/는 것 같다.
2. Fix the error. A learner says 방이 큰는 것 같아요. Correct it.
3. Choose the form. The street is wet and you did not see the rain. Which fits: 비가 온 것 같아요 or 비가 올 것 같아요?
4. Write your own. Write one sentence about a classmate, using -(으)ㄴ/는 것 같아요.

Answer key

1. 먹는 것 같아요. A present verb takes -는.
2. 방이 큰 것 같아요. 크다 is an adjective, so it takes -ㄴ and not -는.
3. 비가 온 것 같아요. The rain is past, so the modifier is -ㄴ.
4. Answers vary. Check that the modifier matches the word class and time. An example: 민수 씨는 오늘 기분이 좋은 것 같아요. ("Min-su seems to be in a good mood today.")

If you can answer items 1 to 3 without the key, you can use the pattern in conversation. Next, the lesson points to related patterns.

What Should You Learn Next after -(으)ㄴ/는 것 같다 Grammar?

After -(으)ㄴ/는 것 같다 grammar, learn the future partner, then the stronger inference pattern. This lesson teaches impressions of the present and past and does not cover future guesses or strong evidence in depth.

1. Start with -(으)ㄹ 것 같다, which covers guesses about the future.
2. Continue with -나 보다, which infers from a clue you noticed. Then read -(으)ㄴ/는 모양이다, the stronger inference from clear evidence.
3. Review the future with future guess -겠- and future tense -(으)ㄹ 거예요.
4. Return to Guessing and Conjecture to see every lesson in this set, or to the Beginner Grammar list for other A1 and A2 patterns.

With these steps, the pattern becomes automatic: pick the modifier for the word class and the time, then add 것 같아요, and keep both spaces.

Frequently Asked Questions

What does -(으)ㄴ/는 것 같다 mean?

-(으)ㄴ/는 것 같다 means "it seems that" or "it looks like." The speaker bases the sentence on something they see, hear or remember. 비가 온 것 같아요 means "It seems it rained," said when the street is wet. It is also a very common way to give an opinion without sounding too sure or too direct.

How do I attach -(으)ㄴ/는 것 같다 to a verb or adjective?

For a present verb, add -는: 가다 becomes 가는 것 같다. For a past verb, add -(으)ㄴ: 가다 becomes 간 것 같다. For a present adjective, add -(으)ㄴ: 크다 becomes 큰 것 같다. For a noun, use -인: 학생인 것 같다. ㄹ stems drop ㄹ, so 살다 becomes 사는 것 같다.

Can -(으)ㄴ/는 것 같다 be used in the past tense?

Yes. A past verb takes -(으)ㄴ: 비가 온 것 같아요. A past adjective takes -았/었던: 어제는 추웠던 것 같아요 means "It seems it was cold yesterday." A past noun takes 이었던 or 였던: 학생이었던 것 같아요. The future is a different pattern, -(으)ㄹ 것 같다.

Is -(으)ㄴ/는 것 같다 used in speech or only in writing?

Both. In everyday speech people say 오는 것 같아요 and often shorten 것 to 거: 오는 거 같아요. In formal speeches and reports they say 오는 것 같습니다. In essays the plain 오는 것 같다 or the more objective 오는 것으로 보인다 appears. The meaning stays the same and only the speech level changes.

What is the most common mistake with -(으)ㄴ/는 것 같다?

The most common mistake is using -(으)ㄹ 것 같다 for a past or present impression. 어제 비가 올 것 같아요 is wrong for "It seems it rained yesterday." Use 어제 비가 온 것 같아요. A second mistake is adding -는 to an adjective, as in 좋는 것 같아요. Adjectives take -(으)ㄴ: 좋은 것 같아요.

Does -(으)ㄴ/는 것 같다 always mean the speaker is unsure?

No. Korean speakers use it as a polite softener even for things they know. 저는 이게 좋은 것 같아요 simply means "I think this one is good" and avoids sounding pushy. When the clue is strong, the pattern sounds like an inference. When the topic is personal taste or opinion, it sounds modest.
