〜かねる

cannot / difficult to (polite)

N1modality

〜かねる expresses cannot / difficult to (polite) — communicating the speaker's degree of certainty, judgment, or attitude about a statement. Modal expressions in Japanese range from strong conviction to vague possibility, and choosing the right one conveys important nuance about how sure you are.

This is a highly advanced pattern found mainly in literary works, formal speeches, legal documents, and academic writing. It is rarely used in casual conversation.

Structure

Verb(ます-stem) + かねる

When to Use#

  • When politely declining or expressing inability
  • When something is regrettably not possible (business/formal)

When NOT to Use#

  • When the meaning is closer to "might / could (negative)" — use 〜かねない instead
  • In casual conversation where a simpler expression would be more natural

Example Sentences#

  • 編集部は未確認の噂を掲載することは承認しかねます。 — The editorial department cannot approve publishing unverified rumors.

Common Mistakes#

  1. Confusing 〜かねる with 〜かねない — While both are related, 〜かねる expresses "cannot / difficult to (polite)" whereas 〜かねない expresses "might / could (negative)." Pay attention to the specific nuance each pattern conveys.
  2. Using 〜かねる in casual conversation — This pattern sounds overly formal or literary in casual speech. Reserve it for formal writing, presentations, or situations that call for elevated language.
  3. Direct translation from English — The concept expressed by 〜かねる may not map one-to-one with its English translation. Focus on understanding the Japanese usage through example sentences rather than relying on the English gloss.
