Nani mo: how do you say "nothing" in Japanese?

Japanese has no word for "nothing." It builds the idea out of three pieces — a question word, も, and a negative verb — and the negative verb is not optional. 何なにも食たべません is "I eat nothing"; 何なにも食たべます is not a sentence.

This is one of the fastest-appearing walls in beginner Japanese, because English hides the structure. "I can't do anything" and "I can do nothing" both exist in English, so learners assume Japanese picks one. It doesn't. It has exactly one shape, and the negative lives on the verb.

The basics

What is the formula?

Take a question word, add も, and make the verb negative. That's the entire pattern.

question word + も + negative verb

何なにも食たべませんでした。 — I didn't eat anything. (polite past) 誰だれも来きませんでした。 — Nobody came. (polite past)

If you already know the question words themselves, you have already learned most of this grammar point — you are just adding a particle and a rule about the verb.

Which question words does it work with?

Question word + も + negative Meaning
何なに (what) 何なにも〜ない nothing
誰だれ (who) 誰だれも〜ない nobody
どこ (where) どこにも〜ない nowhere
どちら / どっち (which of two) どちらも〜ない neither
どれ (which of many) どれも〜ない none of them
何度なんど / 一度いちど (how many times / once) 一度いちども〜ない not even once

どこにも行いきませんでした。 — I didn't go anywhere. (polite past — note the に survives) 一度いちども見みたことがありません。 — I've never seen it, not even once. (polite, emphatic)

What happens to を and が?

They vanish. This is the part textbooks state in one line and then never return to.

を and が are swallowed by も. You never say 何なにをも or 誰だれがも — the も replaces them:

何なにも買かいませんでした。 — I didn't buy anything. (not 何なにをも) 誰だれも知しりません。 — Nobody knows. (not 誰だれがも)

But に, で, と and から survive and stack in front of も:

どこにも行いきたくないです。 — I don't want to go anywhere. (に stays: どこ + に + も) 誰だれとも話はなしませんでした。 — I didn't talk to anyone. (と stays)

The rule is worth memorising as a shape rather than a list: the two particles that mark subject and object disappear; the ones that carry direction or relationship stay. The same logic governs the も that means "also" — it has always been a particle that pushes を and が out of the way.

Beyond the basics

か, も, and でも: one question word, three different words

Change the particle after a question word and you change the whole meaning. Learners memorise these as six unrelated vocabulary items and then can't produce any of them under pressure. They are one system:

何なに 誰だれ どこ
+ か = some- 何なにか (something) 誰だれか (someone) どこか (somewhere)
+ も = no- (negative verb) 何なにも (nothing) 誰だれも (nobody) どこにも (nowhere)
+ でも = any- 何なんでも (anything) 誰だれでも (anyone) どこでも (anywhere)

何なにか食たべましたか。 — Did you eat something? (か — existence unknown) 何なにも食たべていません。 — I haven't eaten anything. (も + negative) 何なんでも食たべます。 — I'll eat anything. (でも — positive, no restriction)

Notice that the middle row is the only one that forces a negative verb. If you can say all three rows for 何なに, you can say them for every question word.

誰だれも with a positive verb means the opposite

Here is the exception that catches intermediate learners. 誰だれも can also appear with a positive verb, where it means "everyone":

誰だれも知しっています。 — Everyone knows. (positive verb — reads as "everybody," not "nobody")

In practice this is rare and mostly literary; modern speech prefers みんな or 誰だれもが. Recognise it, don't produce it. The safe rule for your own sentences stays: use 誰だれも only with a negative.

何なにも vs 何なににも: adding one syllable adds feeling

In casual speech, 何なににも (nan-ni-mo) is an emphatic 何なにも — "not a single thing." It is not a different grammar point, just the spoken intensifier.

何なににもしてないよ。 — I haven't done a thing. (casual, defensive — the extra に carries the protest)

You will hear this constantly in anime the moment a character is accused of something. Compare the flat 何なにもしていません, which reports a fact, with 何なににもしてないよ, which argues.

全然ぜんぜん wants this pattern

全然ぜんぜん ("not at all") is a negative-seeking adverb, and it sits naturally in front of these:

全然ぜんぜん何なにも分わかりません。 — I don't understand anything at all. (polite, emphatic)

Modern casual speech does use 全然ぜんぜん with positives (全然ぜんぜんいいよ = "totally fine"), but that is slang. With a question word + も, the negative is still required.

いつも is not this pattern

いつ means "when," so いつも should mean "never" by the rule above. It doesn't — いつも means always, and it takes positive verbs. It is a frozen, separate word that happens to share the shape.

To say "never," Japanese reaches for a different tool: 一度いちども + negative ("not even once"), 全然ぜんぜん + negative, or the plain negative with 決けっして.

決けっしてあきらめません。 — I will never give up. (formal, emphatic)

Common mistakes

  • Forgetting the negative verb. 何なにも食たべます is not a sentence. If 何なにも, 誰だれも or どこにも appears, the verb must end in ない / ません / なかった / ませんでした.
  • Keeping を or が. 何なにを も食たべません and 誰だれが も来きません are both wrong. も replaces them.
  • Dropping に from どこにも. どこも行いきません sounds broken; どこにも行いきません is the natural form. (どこも on its own does exist — どこも混こんでいる, "everywhere is crowded" — but that is the "everywhere" use, not this one.)
  • Translating "I can't do anything" word by word. English negates the verb and uses "anything." Japanese negates the verb and uses 何なにも. 何なにもできません is the whole sentence — see できる and the potential form for what できません is doing there.
  • Using いつも for "never." いつも is "always." The mismatch feels arbitrary but it is fixed.

Practice

Answers are hidden — write yours first, then open. Questions 3 and 4 are a pair: same idea, and the particle is the only thing that moves.

1. Say "I didn't buy anything" politely, in the past.

Show answer

何なにも買かいませんでした — question word + も + negative verb. The を is gone: not 何なにをも.

2. Something is wrong here: 誰だれが も来きませんでした。

Show answer

誰だれも来きませんでした — も swallows が. Subject and object particles disappear before も.

3. Say "I didn't go anywhere."

Show answer

どこにも行いきませんでした — に survives and stacks in front of も, because it marks direction, not the subject or object.

4. Say "I didn't talk to anyone."

Show answer

誰だれとも話はなしませんでした — と survives too, for the same reason as に in question 3. This is the pair: only が and を vanish.

5. What is the difference between 何なにか食たべましたか and 何なにも食たべましたか?

Show answer

The second one is not a sentence — 何なにか asks "did you eat something?", but 何なにも requires a negative verb, so 何なにも食たべましたか cannot exist. You would need 何なにも食たべませんでしたか.

6. Fill the gap: I'll eat ___ → 何なに_食たべます。

Show answer

何なんでも食たべます — でも is the "any-" row: positive verb, no restriction. も alone would demand a negative.

7. Say "I've never been to Japan" using 一度いちども.

Show answer

日本にほんに一度いちども行いったことがありません — 一度いちども + negative is how Japanese says "never," because いつも is taken and means "always."

8. Why does 何なににもしてないよ sound different from 何なにもしていません?

Show answer

The extra に is emphasis, and the casual ending is a protest — 何なににも means "not a single thing." The polite version reports; the casual one argues back.

9. Something is wrong here: いつも日本にほんに行いきませんでした。(intended: "I have never been to Japan")

Show answer

一度いちども日本にほんに行いったことがありません — いつも means "always," not "never," despite いつ meaning "when." It is a frozen word outside this pattern.

10. Someone asks 何なにか飲のみますか. Refuse politely in one word plus a verb.

Show answer

何なにも飲のみません — the answer flips か to も and the verb to negative. This か → も swap is the most common real-life use of the pattern.

FAQ

Does the negative have to be on the same verb? Yes — on the main verb of that clause. 何なにも食たべたくないです works because the negative sits on たくない. Splitting them across clauses breaks the pattern.

Can I use 何なにも with an adjective? Not directly. 何なにも is a noun-slot word, so it needs a verb. For "nothing is interesting," you would say 何なにも面白おもしろくないです — where 面白おもしろくない is doing the negating and 何なにも is the subject. That works fine.

Is 誰だれも rude compared to 誰だれか? No, they mean different things rather than differing in politeness. 誰だれか is "someone," 誰だれも is "nobody." Register is carried by the verb ending, as always.

Why does どこも sometimes appear without に? Because どこも with a positive verb means "everywhere": どこも人ひとでいっぱいです ("everywhere is packed"). The negative "nowhere" version takes に. Same syllables, different job.

What about なにも in writing — kanji or kana? 何なにも with kanji is standard. 何なににも is usually written the same way and disambiguated by context and speech rhythm.

Is 全然ぜんぜん required for emphasis? No, it just raises the volume. 何なにも分わかりません is already complete; 全然ぜんぜん何なにも分わかりません is "I don't understand a single thing."

I'm Yuuki, a Japanese teacher based in Tokyo. I've taught on italki as a Top 1% teacher and watched over 1,500 anime. This is the pattern I have re-explained more times than any other: a learner reaches for "anything," the verb comes out positive, and the sentence collapses. Once the negative becomes automatic, a whole class of sentences opens up at once.
