〜ことなく (without doing — literary absolute negation)
N1 grammar pattern 〜ことなく: literary 'without doing X' expressing complete, absolute non-occurrence of an action throughout a period. Higher register than 〜ずに or 〜ないで.
〜ことなく
Formality Level: Literary / Formal — literary prose, formal writing, academic writing
Classical Origin: ことなく derives from the classical nominaliser こと (the abstract event/fact of doing X) + なく (classical negative gerundive of ない). The construction means "without the event/fact of doing X occurring." The classical nominaliser こと adds an abstract, distanced quality that makes ことなく more literary and absolute than the functional negative ずに.
Structure
| Form | Example |
|---|---|
| V (dictionary form) + ことなく | 諦めることなく |
| V (dictionary form) + ことなく + [main clause] | 休むことなく研究を続けた |
Meaning
"Without doing X / Not once doing X throughout"
〜ことなく emphasises that X did not occur at all throughout a period or process. It is more literary and absolute than 〜ずに (functional non-performance) and much more formal than 〜ないで (casual non-performance).

When NOT to Use
- Do not use in casual conversation: Use ないで or ずに in spoken contexts.
- Do not use for requests: ❌ 走ることなくください. Use 走らないでください.
- Do not use for very short-duration non-performance: 〜ことなく works best for sustained absence over time or meaningful non-occurrence. For a single moment: use 〜ずに.
