Key facts

• 너무 is a degree adverb that stands directly before an adjective, a verb or another adverb.
• Its original meaning is "too (much)", a degree beyond a limit.
• In modern speech it also means "so" or "very much", with positive words too.
• Formal writing often prefers 아주, 매우 or 정말 for a plain "very".
• 너무하다 is a fixed expression meaning "to be too much" or "to be harsh".

Listen to the two model sentences for this lesson.

The next section defines 너무 and shows its main meanings.

너무 Meaning Too or Very: What Does It Say?

너무 says that the degree is high, and it adds a feeling of excess or strong emotion. A degree adverb is a word that tells how much an adjective or verb applies. Most degree adverbs, such as 아주 ("very"), only state the amount. 너무 adds a judgement: the amount is beyond what is normal, comfortable or expected.

The word has three readings, and the context separates them.

The first reading is the original one. The second reading is common in everyday speech, especially with positive adjectives such as 좋아요 and 예뻐요. The third reading comes from the verb 너무하다, which means "to go too far", and people use it to protest that something is unfair.

A First Example

Here are two sentences that show the first two readings.

The first sentence has a result, 못 먹어요, which shows that the spiciness went beyond a limit, so 너무 means "too". The second sentence has no problem, only praise, so 너무 means "so". The next section shows how to use the word in a sentence.

How Does 너무 Work in a Sentence?

The rule has one step: put 너무 directly before the word it describes. As with other degree adverbs, nothing else changes. 너무 can describe an adjective, a verb of feeling or another adverb.

Pattern Table

The spoken form of 너무 많이 먹었어요 is [너무 마니 머거써요]. The word 너무 stands in the same slot as 아주, as shown in Korean adverb position in a sentence.

Too, so or Very: How to Tell

Readers and listeners use four cues to decide which meaning is intended.

When the cues conflict, the adjective and the speaker's tone decide. 너무 좋아서 믿기지 않아요 ("It is so good that I cannot believe it") ends in a negative, but the adjective is positive, so the meaning is still "so", not "too".

The Too-to Pattern

To say "too ... to do something", use 너무 + reason + 못. The reason ends in -아/어서, which means "because" or "so". The result is a verb with 못 ("cannot") or 안 ("do not"). 너무 매워서 못 먹어요 means "It is too spicy, so I cannot eat it". 너무 비싸서 안 샀어요 means "It was too expensive, so I did not buy it". The word 못 is explained in 못 can't in Korean.

The next section builds one sentence from scratch.

Worked Example: Building 너무 매워서 못 먹어요

To say "It is too spicy to eat", start with the two parts and join them in five steps.

1. Write the reason. The adjective is 맵다 ("spicy"). In the polite present it is 매워요, because 맵다 is a ㅂ-irregular adjective.
2. Add 너무 before the reason. 너무 매워요 means "It is too spicy."
3. Change the reason to the form with -아/어서. 매워요 becomes 매워서 and means "because it is spicy".
4. Add the result. The result is "cannot eat": 못 먹어요. The word 못 stands directly before the verb.
5. Read the whole sentence. 너무 매워서 못 먹어요. In speech, 못 먹어요 sounds like [몬 머거요].

You'll know it worked when 너무 stands before the reason, the reason ends in -서, and the result ends with the verb. To change the sentence from "too" to "so", delete the result: 너무 매워요 can mean "It is so spicy", often with a hint of surprise.

The next section compares 너무 with the other degree words.

How Is 너무 Different from 아주 and 정말?

The three words overlap in positive sentences, and the difference is a matter of feeling and register. 아주 states a high degree. 정말 stresses that the speaker means it. 너무 adds excess or emotion.

With negative or costly things, the choice matters more. 아주 비싸요 states that the price is high. 너무 비싸요 says that the price is too high for you. 정말 비싸요 says that you are sincere about the price. The three sentences have the same grammar, but the listener gets three different messages.

For comparisons such as "more expensive" or "the most expensive", Korean uses different words, which are taught in korean comparatives and superlatives 더 가장. The first lesson in this set, Korean adverbs of degree 아주 너무 정말, gives the full list of degree words.

The next section answers the question that sits behind this page.

Using 너무 with Positive Words

Using 너무 with positive words is accepted in modern Korean. For many years, teachers and dictionaries said that 너무 could only go with negative or excessive things, so 너무 좋아요 was called a mistake. Speakers ignored that rule, and 너무 좋아요 became one of the most common phrases in daily speech. In 2015, the National Institute of Korean Language (국립국어원) revised the entry for 너무 in its Standard Korean Language Dictionary (표준국어대사전) so that the word may also be used in positive sentences.

There is still a register difference. In formal writing, such as reports, speeches and academic texts, many writers choose 매우, 아주 or 정말 for a neutral or positive degree, and keep 너무 for real excess. In speech, messages and social media, 너무 좋아요 and 너무 예뻐요 are normal. A learner can follow this simple rule: use 너무 freely in conversation, and use 아주 or 매우 in a formal essay.

What this lesson does not cover. It does not cover other degree words such as 꽤 and 매우 in depth, mimetic words such as 반짝반짝, or the adverbs made from adjectives. Mimetic adverbs are taught in korean mimetic words adverbs 반짝반짝.

An honest limit. Language authorities and speakers do not always agree on how strong 너무 sounds in a given sentence. The advice about formal writing is a tendency and not a law.

The next section lists the errors that appear most often.

What Mistakes Do Learners Make with 너무?

Learners make five predictable mistakes. Each has a reason and a fix.

Learners often assume 너무 is only negative. Actually it is common with positive words. Wrong idea: avoid 너무 좋아요 and say only 아주 좋아요. Right: both are correct. Fix: use 너무 좋아요 in conversation without worry.

Learners often assume 너무 always means "too". Actually it often means "so". Wrong reading: 너무 맛있어요 as "It is too delicious". Right: "It is so delicious." Fix: check the cues table and look for a problem or result.

Learners often assume 너무 and 아주 are interchangeable. Actually 너무 adds a judgement. Wrong when you only describe the price: 너무 비싸요 for "It is very expensive", because it suggests the price is a problem for you. Right: 아주 비싸요. Fix: use 아주 for a plain degree.

Learners often put 너무 after the word. Actually it stands before. Wrong: 비싸요 너무. Right: 너무 비싸요. Fix: finish the sentence with the predicate.

Learners often stack 너무 with another degree word. Actually one degree word is the norm, and 너무 아주 does not work. Wrong: 너무 아주 좋아요. Right: 너무 좋아요 or 아주 좋아요. Casual speech doubles one word instead, as in 너무너무 좋아요. Fix: pick one degree word.

Practice puts these rules into your own sentences, as the next section shows.

Frequently Asked Questions

What does 너무 mean? 너무 means "too (much)" when something goes beyond a limit, as in 너무 비싸요 ("It is too expensive"). In everyday speech it also means "so" or "very much" with positive words, as in 너무 좋아요 ("It is so good"). The sentence and the situation tell the listener which meaning the speaker intends.

How do I use 너무 in a sentence? Put 너무 directly before an adjective, a verb or another adverb. 비싸요 becomes 너무 비싸요, and 많이 먹었어요 becomes 너무 많이 먹었어요. For "too ... to do", add a reason and 못, as in 너무 매워서 못 먹어요, "It is too spicy to eat."

What is the most common mistake with 너무? The most common mistake is believing that 너무 can only be used with negative words, so learners avoid the natural sentence 너무 좋아요. It is accepted and very common in speech. A second mistake is translating 너무 as "too" every time, which turns 너무 맛있어요 into the odd "It is too delicious".

How is 너무 different from 아주 and 정말? 아주 means "very" and states the degree plainly. 정말 means "really" and stresses sincerity. 너무 means "too" or "so" and adds a sense of excess or strong feeling. 너무 비싸요 hints at a problem, while 아주 비싸요 only states that the price is high. In formal writing, 아주 or 매우 is safer.

Do I use 너무 in speech, writing or both? Both, but speech uses 너무 more freely. In conversation, messages and social media, 너무 좋아요 is normal. In formal writing, reports and speeches, many writers prefer 매우, 아주 or 정말 for neutral or positive degree, and keep 너무 for "too much". A learner can use 너무 safely in speech.
