The term "debriefed" consists of two parts: "de-" and "briefed".
The prefix "de-" in this context carries a sense of removing or reversing an action. It is derived from Middle English, from Old French "de-", which ultimately comes from Latin "de-", meaning "down" or "away".
The term "briefed" comes from the word "brief", which traces its origins to the Old English word "bregdan", meaning "to move quickly or pull suddenly". Over time, "brief" evolved to indicate a concise, summarized statement or instruction. The word "briefed" is derived from the past participle of the verb "to brief", which means to give someone detailed instructions or information about something.
Therefore, "debriefed" essentially means to reverse or undo the act of briefing or providing detailed information.
