“〜dare demo・〜nan demo・〜itsu demo”: Anyone / Anything / Anytime [JLPT N1]

By Nihongo to Japan · Updated July 3, 2026

An expression of free choice and unlimited universality.

“〜dare demo・〜nan demo・〜itsu demo”: Anyone / Anything / Anytime

Question word + でも means “no matter 〜, any 〜 at all” (full affirmation): 誰でも = anyone (やる気があれば誰でもできる = with motivation anyone can), 何でも = anything (何でも相談して = consult me about anything), いつでも = anytime (いつでも連絡して = contact me anytime), どこでも = anywhere, どれでも = any one. It means no exception within that range, all applies. ⚠️ Contrast with ‘question word + も + negative': question word + でも = full affirmation (誰でもできる = anyone can); question word + も + negative = full negation (誰も来ない = no one comes)! でも affirms, も negates.

🧠 Core nuance: within that range, all, no exception

The core is within the range the question word covers, all applies, no exception (full affirmation): question word + でも means ‘no matter …, any … at all' (誰でも = anyone, 何でも = anything, いつでも = anytime, どこでも = anywhere, どれでも = any one), stressing the whole range without exception (誰でもできる = anyone can, 何でもいい = anything is fine, いつでもどうぞ = welcome anytime). ⚠️ Core contrast: 「question word + でも」 = full affirmation (誰でもできる = anyone can); 「question word + も + negative」 = full negation (誰も来ない = no one comes, 何も食べない = ate nothing)! でも goes with affirmation (full affirmation), も goes with negation (full negation). ⚠️ Note: for negation use ‘question word + も,' not ‘でも' (✗ 誰でも来ない → 誰も来ない). ⚠️ Question word + でも is followed by affirmative possibility, permission, welcome (できる, いい, どうぞ). A basic pattern for universality, free choice.

ExpressionUseExample
question word + でも“no matter 〜” (full affirmation)誰でもできる
question word + も + negative“none 〜” (full negation)誰も来ない
question word + か“some 〜” (uncertain)誰か来た
noun + でも“even 〜” (concession)雨でも行く

⚠️ Common Mistakes

  1. Negation uses も not でも: full negation uses ‘question word + も + negative' (誰も来ない), ✗ 誰でも来ない.
  2. でも full affirmation, も negation: question word + でも = full affirmation (誰でもできる); question word + も + negative = full negation (誰も〜ない).
  3. Distinguish from question word + か: でも = any at all (comprehensive); か = some (uncertain, 誰か).
  4. Followed by affirmation: question word + でも is followed by affirmative possibility/permission (できる, いい, どうぞ).

💡 Nuance & When to Use

Question word + でも means “no matter 〜, any 〜 at all” (full affirmation): 誰でも (anyone), 何でも (anything), いつでも (anytime), どこでも (anywhere), どれでも (any one), stressing no exception within the range. ⚠️ Core contrast: question word + でも = full affirmation (誰でもできる); question word + も + negative = full negation (誰も来ない). For negation use も not でも. Distinguish from the ‘some …' question word + か and the concession noun + でも. A must at N1 (foundation reinforcement).
