Did you know?

Gather together various documents relating to the affairs of a certain individual, sort them into separate folders, label the spine of each folder, and arrange the folders in a box. Dossier, the French word for such a compendium of spine-labeled folders, was picked up by English speakers in the 19th century. It comes from dos, the French word for "back." The verb endorse (which originally meant "to write on the back of") and the rare adjective addorsed ("set or turned back to back," a term primarily used in heraldry) are also derived, via the Anglo-French endosser and French adosser respectively, from dos. The French dos has its origins in the Latin dorsum, a word which also gave English the adjective dorsal ("situated on the back"), as in "the dorsal fin of a whale."
