Other forms: dossiers
A dossier is a file of collected information about somebody. Compile a dossier, a thick dossier, a dossier on him.
The word carries a whiff of surveillance that file does not — a dossier is assembled about a person, usually without their knowing. It is French, and the name comes from the bulge on the spine of a bundle of papers, from dos, the back. Note the pronunciation, which keeps the French shape.
