Usage notes

• In the above sentences, ずに and ないで (naide) are interchangeable. However, in the following sentences, ないで must be used, because ずに is grammatically incorrect.

  まだ帰(かえ)らないでください。 ― mada kaeranaide kudasai. ― Please don’t go home yet.

  電(でん)話(わ)しないで欲(ほ)しい。 ― denwashinaide hoshī. ― Lit. I want you not to call me. (Fig. Don’t call me.)

  見(み)ないでください。 ― minaide kudasai. ― Please do not look at it.

• ずに has the exact same formation as ないで in almost all cases. The sole exception is the verb する (suru), which changes from しないで (shinaide) to せずに (sezuni).
• The difference between ないで and ずに is that ないで is used in informal speech or conversational Japanese, whereas ずに is used in formal speech or written Japanese.
• For the following sentences in which the ないで clause indicates some cause for human emotion that is expressed in the main clause, なくて (nakute) can replace ないで, but not ずに.

  僕(ぼく)は英(えい)語(ご)が話(はな)せないで恥(は)ずかしかった。 ― boku wa eigo ga hanasenaide hazukashikatta. ― I felt ashamed because I couldn’t speak English.

  スージーが遊(あそ)びに来(こ)ないでほっとした。 ― sūjī ga asobi ni konaide hottoshita. ― I felt relieved because Susie didn’t come to play.

• For sentences that express the idea of “X is not Y but X,” neither ないで nor ずに can replace なくて.

  私(わたし)は学(がく)生(せい)ではなくて先(せん)生(せい)です。 ― watashi wa gakuseide wa nakute sensei desu. ― I am not a student but a teacher.
