IPA: /dɪˈbrifɪŋ/
KK: /dɪˈbrifɪŋ/
The process of questioning someone after an event to gather information about what happened.
After the mission, the team went through a debriefing to discuss their experiences and findings.
Debriefing → It is formed from "de-" (meaning down or away) and "brief" (from Latin "brevis", meaning short). The word refers to the process of providing a summary or report after an event, essentially taking away the essential information in a concise manner.
Think of 'taking away' ('de-') the 'short' summary ('brief') after an event — that's what debriefing means.
