Pattern

  • 名詞+の+最中に noun + の + 最中に (食事の最中に)
  • 動詞ている形+最中に verb ている-form + 最中に (話している最中に)

Meaning and use

As in 会議の最中に停電した, it says that something else happened suddenly while something was in progress. What follows is often unexpected and unwelcome for the speaker (the phone rang, the power went out, my mind went blank).

Compared with ときに

ときに merely marks a time, but 最中に stresses being right in the middle and carries a sense of interruption. The second half is a sudden event rather than a deliberate action. The first half must be an action or event that lasts for a while, not an instant.

Examples

  • 食事(しょくじ)の最中(さいちゅう)に、電話(でんわ)が鳴(な)った。

    Shokuji no saichū ni, denwa ga natta.

    The phone rang in the middle of the meal.

    An interruption during the meal.

  • 会議(かいぎ)の最中(さいちゅう)に、急(きゅう)に停電(ていでん)した。

    Kaigi no saichū ni, kyū ni teiden shita.

    Right in the middle of the meeting, the power suddenly went out.

    A sudden trouble.

  • 発表(はっぴょう)の最中(さいちゅう)に、頭(あたま)が真(ま)っ白(しろ)になった。

    Happyō no saichū ni, atama ga masshiro ni natta.

    Right in the middle of my presentation, my mind went blank.

    Something unwelcome happening to the speaker.

Common mistakes

  • Nouns need の, and verbs take the ている form: 話している最中に.
  • Do not follow it with your own deliberate action: × 食事の最中に、電話をかけよう.
