Nomenclature
The word "raccoon" is derived from the Algonquian word aroughcoune, "he who scratches with his hands." Spanish-speaking colonists similarly adopted their term, mapache, from the Nahuatl word for the animal, meaning roughly "that which has hands".
The genus name, Procyon, comes from the Greek for "before the dog"; this term is also used for the star Procyon of the constellation Canis Minor.
Raccoons are today understood to have a relatively loose evolutionary relationship with bears, which was nonetheless seen as significant by the early taxonomists; Carolus Linnaeus initially placed the raccoon in the genus Ursus. In many languages, the raccoon is named for its characteristic dousing behavior in conjunction with that language's term for "bear": Waschbär in German, mosómedve in Hungarian, vaskebjørn in Danish and Norwegian, tvättbjörn in Swedish, wasbeer in Dutch, pesukarhu in Finnish, araiguma (アライグマ) in Japanese, orsetto lavatore in Italian, huànxióng (浣熊) in Chinese and mieshta mechka (миеща мечка) in Bulgarian all mean "washing bear". One exception is Russian, where raccoon is named yenot (енот) due to similarity between raccoon and genet furs. However, the full name of the common raccoon in Russian is also “water-related”: it is called yenot-poloskun (енот-полоскун), which means "rinsing raccoon".
In some cases, the "washing" descriptor is applied only to the common raccoon species: for example, in French the common raccoon is called raton laveur or "washing rat," while its Linnaean binomial is Procyon lotor or, roughly, "washing pre-dog." In contrast, the crab-eating raccoon is "little crab-catching rat" (raton crabier) and "crab-eating pre-dog" (Procyon cancrivorus) in French and Latin, respectively.
