The Particle “mo”: Also, Likewise, Emphasis, Total Negation [JLPT N5]
By Nihongo to Japan · Updated July 3, 2026
「私も行く」「何もない」「どこにも行かない」 — one も changes a sentence's whole scope of coverage.
The Particle “mo”: Also, Likewise, Emphasis, Total Negation
The particle 「も」 has three main uses: ① “also, likewise” (adding the same situation): 「私も行く」 (I'll go too), 「これもください」 (this one too, please); ② question word ＋ も ＋ negative “total negation” (none at all): 「何もない」 (there's nothing), 「どこにも行かない」 (don't go anywhere), 「誰もいない」 (no one's there); ③ emphasizing quantity “as much/many as” (emphasizing a lot/long): 「三時間も待った」 (waited as long as three hours). ⚠️ Key: question word ＋ も ＋ negative = total negation (何も…ない); question word ＋ でも = full affirmation (何でも = anything)! ⚠️ Note: も replaces が/を (✗ 私もが→私も), but with に/で it's added (どこにも, これでも).
🧠 Core nuance: the scope of coverage, sameness, emphasis
The core is も's three functions, changing a sentence's scope of coverage: ① ‘also, likewise' — expressing adding the same situation (A is, B is too: 私も行く = I'll go too, 彼も学生だ = he's a student too, これもください = this one too); ② question word ＋ も ＋ negative ‘total negation' — expressing none at all (何も食べない = ate nothing, 誰も来ない = no one comes, どこにも行かない = don't go anywhere, 一つもない = not even one); ③ emphasizing quantity ‘as much/many as' — emphasizing a large quantity/long time, unexpectedly (三時間も待った = waited as long as three hours, 十人も来た = as many as ten came). ⚠️ Core contrast: 「question word ＋ も ＋ negative」 = total negation (誰も来ない = no one comes, 何もない = there's nothing); 「question word ＋ でも」 = full affirmation (誰でもできる = anyone can, 何でもいい = anything is fine)! も with negation (total negation), でも with affirmation (full affirmation). ⚠️ Note: も replaces the subject が, object を (✗ 私はも→私も, ✗ これをも→これも); but with に/で/と etc. it's added after (どこにも行かない, これでもいい). ⚠️ Pattern 「〜も〜も」 (both: AもBも = both A and B). A core N5 particle.
📌 Three Uses
| Use | Form | Example |
|---|---|---|
| also, likewise | noun ＋ も | 私も行く |
| total negation | question word ＋ も ＋ negative | 何もない |
| emphasizing quantity | quantity ＋ も | 三時間も待った |
| (contrast) question word ＋ でも | full affirmation | 誰でもできる |
💬 Example Sentences
- A: 私は納豆が嫌いです。B: 私も嫌いです。(A: I dislike natto. B: I dislike it too.) — also, likewise
- 昨日は何も食べませんでした。(I ate nothing yesterday.) — total negation
- 田中さんも山田さんも来ました。(Both Tanaka and Yamada came.) — も〜も (both)
- 三時間も待ちました!(I waited as long as three hours!) — emphasizing quantity
- どこにも行きたくない。(I don't want to go anywhere.) — total negation (with に)
🔄 Compare: も vs は vs question word ＋ も ＋ negative vs question word ＋ でも
| Expression | Nuance | Example |
|---|---|---|
| も | also, likewise (adding the same) | 私も行く |
| は | topic (contrast, marking) | 私は行く |
| question word ＋ も ＋ negative | total negation (none) | 何も食べない |
| question word ＋ でも | full affirmation (any) | 何でも食べる |
⚠️ Common Mistakes
- question word ＋ も ＋ negative = total negation: 何も…ない, 誰も…ない, どこにも…ない (none at all).
- も vs でも: question word ＋ も ＋ negative = total negation; question word ＋ でも = full affirmation (誰でもできる) — don't confuse!
- も replaces が/を: ✗ 私はも→私も, ✗ これをも→これも; with に/で it's added after (どこにも, これでも).
- Emphasizing quantity: quantity ＋ も = as much/many as (三時間も待った).
💡 Nuance & When to Use
The particle 「も」 has three uses: also/likewise (私も行く), total negation (question word ＋ も ＋ negative: 何もない, 誰も来ない), emphasizing quantity (三時間も待った = waited as long as three hours). ⚠️ Core contrast: question word ＋ も ＋ negative = total negation; question word ＋ でも = full affirmation (何でも). も replaces が/を, added after に/で. Pattern AもBも (both). A core N5 particle. A must.
🎯 JLPT Exam Tips
- N5 core: も = also/likewise (私も), total negation (question word ＋ も ＋ negative: 何もない), emphasizing quantity (三時間も).
- Most important contrast: question word ＋ も ＋ negative (total negation: 誰も来ない) vs question word ＋ でも (full affirmation: 誰でもできる).
- Note: も replaces が/を; with に/で added after (どこにも, これでも); AもBも = both.

Answer Key

2. (C) 何も ── ‘question word ＋ も ＋ negative' = total negation: 何も食べなかった = ate nothing.
3. (B) いつでも ── ‘question word ＋ でも' = full affirmation: いつでも = any time.
4. (D) も・も ── AもBも = both A and B.
5. (B) ── quantity ＋ も emphasizes a large amount: 三時間も = as long as three hours (with surprise).
