“〜koso are / 〜koso sure”: There Is Only 〜, Never 〜 (Emphatic Adversative) [JLPT N1]

By Nihongo to Japan · Updated July 3, 2026

Negating the general case, affirming the specific one.

“〜koso are / 〜koso sure”: There Is Only 〜, Never 〜 (Emphatic Adversative)

「〜こそあれ/こそすれ」 expresses ‘there is only A, never B' — using 「こそ」 to emphasize-affirm A (the first), thereby strongly negating B (the latter); a highly formal written, oratorical expression. E.g. 「感謝こそすれ、批判する気はない」 (there is only gratitude, no intention to criticize), 「不満こそあれ、不正はしない」 (there may be dissatisfaction, but I'd never act dishonestly). ⚠️ Connection: こそあれ attaches to a noun/な-adjective stem (不満こそあれ); こそすれ attaches to a verb stem (感謝しこそすれ)! ⚠️ Structure: ‘AこそあれB〜ない' = affirming A to strongly negate B (there may be A, but never B). ⚠️ Highly formal, written, oratorical; rarely used in speech.

🧠 Core nuance: affirm A to strongly negate B

The core is using 「こそ」 to emphasize-affirm the first A, thereby strongly, decisively negating the latter B: ‘there is only A, never B': the structure is ‘AこそあれB〜ない' or ‘AこそすれB〜ない,' emphasizing A (‘it's precisely A, A indeed exists') to highlight the contrast ‘there is absolutely no B' (感謝の気持ちこそあれ、恨みなど全くない = there is only gratitude, absolutely no resentment, 進歩こそすれ、後退することはない = it will only progress, never regress, 苦労こそあれ、後悔はしていない = there may be hardship, but no regret). ⚠️ Core: this is an emphatic adversative — ‘there indeed is A (affirmation), but absolutely no B (strong negation),' where A is usually something the speaker is willing to admit, B something to decisively deny. ⚠️ Connection (important): 「こそあれ」 attaches to a noun, な-adjective stem (不満こそあれ, 立派でこそあれ); 「こそすれ」 attaches to a verb stem (感謝しこそすれ, 増えこそすれ)! ⚠️ Register: highly formal, written, oratorical, rarely used in speech (the register of essays, addresses, solemn declarations). ⚠️ Contrast with 「どころか」: どころか also means ‘far from …, on the contrary' (adversative), but こそあれ/こそすれ is more literary, emphasizing the affirm-A-negate-B contrast more. An N1 emphatic-adversative written expression.

⚠️ Common Mistakes

  1. Connection: こそあれ attaches to a noun/な-adjective stem (不満こそあれ); こそすれ attaches to a verb stem (感謝しこそすれ, ✗ 感謝するこそすれ)!
  2. The structure affirms A, negates B: AこそあれB〜ない (affirming A to strongly negate B), the latter is negative.
  3. Highly formal, written: こそあれ/こそすれ is a written, oratorical expression, rarely used in speech.
  4. Don't confuse with こそ: こそ alone is emphasis (今こそ); こそあれ/こそすれ is an emphatic-adversative pattern.

💡 Nuance & When to Use

「〜こそあれ/こそすれ」 expresses ‘there is only A, never B,' using こそ to emphasize-affirm A to strongly negate B (感謝こそすれ批判しない, 不満こそあれ不正はしない). ⚠️ Connection: こそあれ attaches to a noun/な-adjective stem, こそすれ to a verb stem. Highly formal, written, oratorical, not used in speech. Contrast with どころか (far from …, on the contrary). An N1 emphatic-adversative written expression — memorize it.
