Without Doing: ないで and ずに

In Japanese, the expressions ないで (naide) and ずに (zuni) are used to indicate doing something without performing another action. These structures are useful for expressing actions that are done without performing a preceding action, often translating to "without doing" in English. While both forms are similar, they have their distinct usages and nuances.

ないで (naide)

ないで is used to express that an action is performed without doing something else. It is attached to the negative form of a verb.

テレビ を みないで べんきょう します。 - I study without watching TV.

かさ を もたないで でかけました。 - I went out without taking an umbrella.

ずに (Zuni)

ずに serves a similar function as ないで but is more formal and often used in written language. It is derived from the classical Japanese conjugation and is used by attaching ずに to the stem of the verb.

たべずに ねました。 - I went to sleep without eating.

いわずに でかけました。 - I went out without saying anything.
