What does dossier mean?

A dossier is a collection of detailed information about a person or other subject.

The word dossier is popularly associated with espionage, law enforcement, and politics. When used in these contexts, it often refers to a file that includes all the “dirt” on someone (such as secret negative information that could be used to blackmail them).

Example: We’ve been tracking this guy for years—we have a 2,000-page dossier on him.

Where does dossier come from?

Dossier comes directly from French, in which it specifically means a “a bundle of papers with a label on the back.” (In French, dos means “back.”) Dossier has been used in English since at least the late 1800s.

Dossier just means “a collection of documents about the same topic.” Dossiers are typically meant to provide comprehensive, detailed information about a subject. In crime TV shows, when a detective hands another detective a thick folder that’s filled with documents about a suspect’s criminal record (usually with their photo paper-clipped to the front), that’s a dossier (though on TV they often just call it a file). But movies and real-life intrigue have made dossier become closely associated with the kind of secret files compiled by spy agencies and political operatives. In this sense, dossiers often contain things like intercepted emails, hidden bank records, and secretly taken photos of the target in compromising positions.

Still, in general, a dossier can be a file on any single subject. It can contain information on a particular organization, business, or any topic—not just an individual person.
