即座

1. Origins, structure, and basic meaning

• Structure: 即座 (reading そくざ) is a noun expressing an immediate, on-the-spot response without delay or hesitation.
• Basic usage: It commonly appears as 即座に when a device is stopped at once or a correct answer is returned on the spot.

2. Common pitfalls and similar expressions

• Adverbial form
  • Add に before an action, as in 即座に止める or 即座に答える.
• Focus beside 直ちに
  • Both can mean immediately, but 即座に particularly highlights a response produced right there and then.
