Forming it

Basic form離陸した → 離陸したかと思ったら

How to use it

Two events follow each other in an instant, surprising the speaker. The second clause states something that already happened.

  • 「Vたかと思ったら」 = no sooner had A happened than B: 「離陸したかと思ったら、飛行機が揺れ始めた」.
  • The second clause does NOT use volitional, imperative, or invitational forms — it only describes something that happened unexpectedly.
  • Not used for one's own actions: 「私は家に着いたかと思ったら、寝てしまった」 sounds odd because the speaker must be observing from the outside.

Examples

  • No sooner had we taken off than the plane began shaking violently.

  • The child had barely come home before running out to play again.

Keep in mind

  • Connects to the た form.
  • The following clause is something that already happened, not an intention.
