📝 Conjugation Notes
Attach to the ない form of verbs (e.g., する → せず/しない → することなく; 食べる → 食べない → 食べることなく; 来る → 来ない → 来ることなく). Note irregular verbs like する and 来る can also use せずに and 来ずに, which might influence how 〜ことなく is felt, though ことなく always attaches to the standard ない-form.
🔊 Pronunciation Tips
Pronounced smoothly, almost as one unit. The emphasis is typically on the verb before ことなく.
🧠 Memory Tips
Think of こと (koto – thing/matter) + なく (naku – without). “Without the matter/act of doing X.” This highlights the *absence* of the action X.
