The word "beaver" may refer both to the genus Castor, the species Castor fiber and the species Castor canadensis. Andres 09:53, 12 Jul 2004 (UTC)
The Breton counterpart seems to refer strictly to Castor fiber. Probably the generic word is avank. Andres 10:01, 12 Jul 2004 (UTC)
The Latin counterpart is the scientific name of one of two beaver species. The scientific name of the genus is Castor, the common word for beaver is castor. Andres 10:19, 12 Jul 2004 (UTC)
Most other dictionaries also note that "beaver" is an accepted alternate plural form.
- A possibly different "beaver hat" is mentioned by Chaucer in both Canterbury Tales and Testament of Creeside, and indeed much earlier in Normandy Chronicle of the Abbey of St Wandrille refers to a hat given before 833 as "quem vulgaris Bevurum".
