neutralformal

To question (someone, typically a soldier or spy) about a completed mission or undertaking. (As a noun) A session of debriefing.

Debriefing is a structured process of extracting information from someone after an event or mission. It's not just a casual chat, but a formal interview to gather intelligence, assess performance, and ensure all details are captured.

The story behind the word. The word 'debrief' is a relatively modern English creation, appearing in the mid-20th century. It's formed by adding the prefix 'de-' (meaning 'undo' or 'reverse') to the word 'brief.' To 'brief' someone is to give them instructions or information before a mission. Therefore, to 'debrief' is to 'un-brief' them, or rather, to extract information from them after the mission is complete. It perfectly encapsulates the reversal of the information flow.
