Because we left the campsite without eating breakfast, I got hungry.

Why it means that

Describe an action performed without another

~ずに means "without doing..." (formal equivalent to ~ないで). It describes an action skipped or omitted while performing another.

Examples

彼かれは何なにも言いわずに帰かえった。

kare wa nani mo iwazu ni kaetta.

He went home without saying anything.

辞書じしょを使つかわずにこの本ほんを読よんだ。

jisho o tsukawazu ni kono hon o yonda.

I read this book without using a dictionary.

How it is built

Replace ない with ずに

Take the verb's negative form (ない-form), drop ない, and attach ずに. Irregular: する becomes せずに (not しずに). Can also appear as plain ず at a clause break.

verb (ない-stem)+ずに
Example

諦あきらめずに最後さいごまで練習れんしゅうを続つづけた。

akiramezu ni saigo made renshuu o tsuzuketa.

Without giving up, I continued practicing until the end.

Compare

~ないで vs ~ずに

Both mean “without doing”. ~ないで is the everyday form. ~ずに means the same but sounds a little more formal, so it is common in writing and careful speech. For する, use せずに.

  • ~ないで, without (everyday)

    傘かさを持もたないで出でかけた。

    kasa o motanaide dekaketa.

    I went out without taking an umbrella.

    Natural in conversation.

  • ~ずに, without (more formal)

    傘かさを持もたずに出でかけた。

    kasa o motazu ni dekaketa.

    I went out without taking an umbrella.

    Same meaning, a little more formal.
