席せきを取とっておく

expression, godan verb (-ku)

reserve a seat; book a seat

Literally 'to take and put a seat aside', i.e., to reserve or hold a seat for someone. It is a rare term; in modern Japanese, 席を予約する or 席を取る are more common for booking, while 席を取っておく can imply holding a seat informally.

• いい席せきを取とっておいてくれてありがとう。

  Thank you for saving a good seat for me.

• コンサートの席せきを取とっておくのを忘わすれないで。

  Don't forget to reserve seats for the concert.
