"No one came." "There's nothing here." "I don't want any of it." In English these carry the negation inside the noun phrase — "no one," "nothing," "none." Korean does it differently: it builds the noun as 아무도 / 아무것도 and then still requires a negative predicate at the end of the clause. 아무도 by itself does not mean "anyone"; it means "no one" — and it is ungrammatical unless the verb is negated. These are the noun-phrase members of the negative-polarity family, the counterparts to the adverbs 전혀 / 별로.
The single most useful discovery on this page is that the very same stem 아무 flips between "no-" and "any-" depending on one particle: attach 도 and negate, and you get "no one / nothing / nowhere"; attach 나 and stay positive, and you get "anyone / anything / anywhere." The stem is neutral; the particle sets the polarity. Get that switch and a whole corner of Korean opens up.
The 아무-series: 아무 (+ noun) + 도 + negation
The template is fixed: 아무 + (noun) + 도 + [negated predicate]. The 도 (here the "even / also" particle pressed into service as "not even") is obligatory, and the clause must end in a negator — 안, -지 않다, 못, or the lexical 없다.
| Form | Meaning | Typical negator |
|---|---|---|
| 아무도 | no one (people) | 안 / 없다 |
| 아무것도 | nothing (things) | 안 / 없다 |
| 아무 데도 | nowhere (places) | 안 / 없다 |
| 아무 말도 | not a word | 안 / -지 않다 |
| 아무한테도 | to no one | 안 / -지 않다 |
교실에 아무도 없어요.
gyosire amudo eopseoyo
There's no one in the classroom.
어제는 아무도 안 왔어요.
eojeneun amudo an wasseoyo
Nobody came yesterday.
냉장고에 아무것도 없어요.
naengjanggoe amugeotdo eopseoyo
There's nothing in the fridge.
아침부터 아무것도 안 먹었어요.
achimbuteo amugeotdo an meogeosseoyo
I haven't eaten anything since morning.
주말에 아무 데도 안 갔어요.
jumare amu dedo an gasseoyo
I didn't go anywhere over the weekend.
그 사람은 아무한테도 아무 말도 안 했어요.
geu sarameun amuhantedo amu maldo an haesseoyo
That person didn't say a word to anyone.
That last one stacks two 아무-…-도 phrases under a single negated verb (했어요 → 안 했어요) — perfectly natural, and a nice demonstration that one negator licenses everything in the clause.
There is a register split worth flagging. Colloquial Korean overwhelmingly prefers the 아무-series — 아무도, 아무것도 — for "no one / nothing." A parallel set built on the plain question words (누구도 "no one," 무엇도 "nothing," 어느 누구도 "not a single soul") also exists and follows the identical 도 + negation rule, but it belongs to formal and written register: news, speeches, essays. So 파티에 아무도 안 왔어요 in conversation, but 그 사실은 누구도 몰랐다 "no one knew that fact" in an article. Reach for 아무도 when you speak and recognize 누구도 when you read.
하나도: "not even one / not in the least"
하나도 is literally "even one," and with a negator it becomes an intensifier of total negation — "not a single one," or, extended to non-count things, "not in the slightest." It is the go-to way to say "not at all" about quantities and sensations.
이 김치는 하나도 안 매워요.
i gimchineun hanado an maewoyo
This kimchi isn't spicy at all.
빵이 하나도 안 남았어요.
ppang-i hanado an namasseoyo
There's not a single piece of bread left.
무슨 말인지 하나도 모르겠어요.
museun marinji hanado moreugesseoyo
I don't understand a word of it.
Notice 하나도 안 매워요: nothing is being counted (spiciness isn't a countable thing), yet 하나도 still works, exactly like English "not one bit." Like every item in this family, it needs the negator — ✗하나도 매워요 is broken.
절대(로): "absolutely (not) / never"
절대 (also 절대로, with the adverbial 로) means "absolutely / under no circumstances." It is the emphatic partner of prohibitions and refusals, and it strongly prefers a negative or prohibitive predicate — 안, -지 않다, 못, or the prohibition -지 마.
그건 절대로 안 돼요.
geugeon jeoldaero an dwaeyo
That's absolutely not allowed.
이 일은 절대 잊지 않을 거예요.
i ireun jeoldae itji aneul geoyeyo
I will never forget this.
힘들어도 절대로 포기하지 마.
himdeureodo jeoldaero pogihaji ma
No matter how hard it gets, never give up. (casual, to a friend)
That last example pairs 절대로 with the prohibition -지 마, the negative command "don't." 절대 supplies the "under no circumstances" force; -지 마 supplies the prohibition. Together they make an emphatic "never."
The 도/나 switch: 아무도 vs 아무나
Now the payoff. The stem 아무 (and its cousin 누구) is not inherently negative. What makes it "no one" is the combination 도 + negation. Swap 도 for 나 and drop the negation, and the exact same stem becomes "anyone / anything / anywhere" with a positive predicate. One stem, two opposite meanings, decided entirely by the particle.
| 도 + negation → "no-" | 나 + positive → "any-" |
|---|---|
| 아무도 안 와요 (no one comes) | 아무나 와도 돼요 (anyone may come) |
| 아무것도 없어요 (there's nothing) | 아무거나 괜찮아요 (anything's fine) |
| 아무 데도 안 가요 (goes nowhere) | 아무 데나 가요 (goes anywhere) |
| 누구도 모르는 일 (a thing no one knows — formal) | 누구나 아는 일 (a thing everyone knows) |
아무나 와도 돼요.
amuna wado dwaeyo
Anyone can come.
저는 아무거나 다 잘 먹어요.
jeoneun amugeona da jal meogeoyo
I'll happily eat anything.
This is where English speakers go wrong most often. English "anyone" and "anything" are positive-compatible ("anyone can come," "call me anytime"), so learners map them straight onto 아무도 / 아무것도 and then attach a positive verb — producing ✗아무도 왔어요 for "someone came." But 아무도 can only mean "no one." "Someone came" is 누가 왔어요; "anyone can come" is 아무나 와도 돼요. The indefinite uses of question words page covers the positive 아무나 / 누구나 side in depth.
Common Mistakes
1. Pairing 아무도 / 아무것도 with a positive verb. These are negative-only.
❌ 파티에 아무도 왔어요.
Incorrect — 아무도 means 'no one' and demands negation. For 'someone came' use 누가 왔어요.
✅ 파티에 아무도 안 왔어요.
patie amudo an wasseoyo
No one came to the party.
2. Dropping the obligatory 도. The polarity item is the whole 아무…도 package.
❌ 냉장고에 아무것 없어요.
Incorrect — 아무것 needs 도: 아무것도 없어요.
✅ 냉장고에 아무것도 없어요.
naengjanggoe amugeotdo eopseoyo
There's nothing in the fridge.
3. Confusing 아무도 (no one) with 아무나 (anyone). The particle sets the polarity.
❌ 이 일은 아무도 할 수 있어요.
Contradictory — 아무도 + positive. For 'anyone can do this' use 아무나 할 수 있어요.
✅ 이 일은 아무나 할 수 있어요.
i ireun amuna hal su isseoyo
Anyone can do this.
4. Using 하나도 as a plain "one." 하나도 means "not even one" and needs a negator; a plain quantity "one" is just 하나.
❌ 사과가 하나도 있어요.
Incorrect — 하나도 requires negation ('not even one'); for 'there's one apple' say 사과가 하나 있어요.
✅ 사과가 하나도 없어요.
sagwaga hanado eopseoyo
There's not a single apple.
5. Leaving 절대(로) with a bare positive in careful speech. Keep 절대 paired with a negator or prohibition.
❌ 저는 절대로 그렇게 해요.
Incorrect in careful Korean — 절대로 wants a negator: 절대로 그렇게 안 해요.
✅ 저는 절대로 그렇게 안 해요.
jeoneun jeoldaero geureoke an haeyo
I would never do it that way.
Key Takeaways
- 아무도, 아무것도, 아무 데도, 아무 말도 are negative-polarity nouns: 아무 + noun + 도
- a negated predicate. All three parts are required.
- 하나도 = "not even one / not in the least" (intensified total negation); 절대(로) = "absolutely not / never," the partner of prohibitions.
- The stem 아무 (and 누구) is polarity-neutral: 도 + negation → "no-", 나 + positive → "any-". 아무도 안 와요 vs 아무나 와도 돼요.
- English "anyone/anything" are positive-compatible; 아무도/아무것도 are not — "someone came" is 누가 왔어요, "anyone can come" is 아무나 와도 돼요.
- One negator at the end of the clause licenses every 아무…도 phrase inside it.
