“〜demo・〜ka”: Even / Or / Any — A Complete Guide [JLPT N4]
Content by NTJ Kuma · Nihongo to Japan editorial team · Updated July 27, 2026
「何でも食べる」vs「何か食べる」 — でも = “any at all,” か = “some / or.”
「何でも」 vs 「何か」 — one syllable, opposite meanings
「何でも食べる」 means “I eat anything,” but 「何か食べる」 means “I'll eat something” — one syllable apart, nearly opposite meanings. The rule in a line: question word ＋ でも = any… (all-inclusive), question word ＋ か = some… (unspecified). Add 「noun か noun = … or … (choice)」 and you have three high-frequency N5 points, sorted in one go.
Three cores: でも (all) / か (some) / か (or)
- question word ＋ でも = any… (fully inclusive, no exceptions): 何でも (anything), どこでも (anywhere), 誰でも (anyone), いつでも (anytime).
- question word ＋ か = some… (it exists, but which is unspecified): 誰か (someone), 何か (something), どこか (somewhere), いつか (someday).
- noun か noun = … or … (choice): コーヒーか紅茶 (coffee or tea).
Mnemonic: でも spreads out to cover everything; か shrinks to one unspecified point.
How to Connect
| Form | Use | Example |
|---|---|---|
| question ＋ でも | any… (all) | 何でも・どこでも |
| question ＋ か | some… (unspecified) | 誰か・何か |
| noun ＋ か ＋ noun | … or … (choice) | コーヒーか紅茶 |
| noun ＋ でも | even… (concession) | 雨でも行く |
Example sentences
- 何でも食べていいですよ。(You can eat anything.) — question ＋ でも (any)
- どこでも連れて行ってください！(Take me anywhere!) — any
- 誰か来たみたいだ。(Someone seems to have come.) — question ＋ か (someone)
- コーヒーか紅茶、どちらがいい？(Coffee or tea — which would you like?) — noun か noun (or)
- 週末、どこか行きたいな。(I'd like to go somewhere this weekend.) — somewhere
⚠️ Where learners slip up
① でも and か are opposites — don't swap them. 何でも = anything (all-inclusive); 何か = something (a little, unspecified). “何でも食べる (I'll eat anything)” is worlds apart from “何か食べる (I'll eat something).”
② か can also mean “whether.” 「誰か来るか確認する」 = check whether anyone is coming — the second か is an embedded question, not “some.” One sentence can hold two か's doing different jobs.
🔄 Nuance & comparison: でも / か / も
| Form | Use | Example |
|---|---|---|
| question ＋ でも | any… (all, affirmative) | 何でも食べる （eats anything） |
| question ＋ か | some… (unspecified) | 何か食べる |
| question ＋ も ＋ negative | not any… (all, negative) | 何も食べない （doesn't eat anything） |
💡 The key point in use
One line does it: でも is “all,” か is “some,” も ＋ ない is “none.” 何でも (anything) / 何か (something) / 何も食べない (nothing) — read the three side by side and the nuance snaps apart. Tests love to trap you on 「何でも vs 何か」, so when you see it, ask: all, or some?
❓ FAQ
Q: 「誰か」 vs 「誰でも」?
「誰か」 = someone (identity unknown; 誰か来た = someone came); 「誰でも」 = anyone at all (誰でもできる = anyone can do it). One is an unspecified single person, the other is everyone.
Q: What's 「何も」?
「question word ＋ も ＋ negative」 = full negation: 何も食べない (eat nothing), 誰も来ない (no one comes). The exact opposite of the all-affirmative でも.

1. (B) でも ── question word (何) + でも = anything at all. 「何でも食べる」 = eat anything. question word + か = some uncertain thing.
2. (B) か ── AかB = A or B (a choice). コーヒーか紅茶 = coffee or tea.
3. (C) か ── 「誰か来るか」 = whether someone is coming (an embedded question). 「誰か」 = someone.
4. (A) でも ── noun (雨) + でも = even if it rains. でも for concession.
5. (C) でも ── question word (どこ) + でも = anywhere at all. 「どこでも連れて行って」 = take me anywhere.
