From Middle English bever, from Old English befer, from Proto-West Germanic *bebru, from Proto-Germanic *bebruz, from Proto-Indo-European *bʰébʰrus (“beaver”). Cognate with West Frisian bever, Dutch bever, French bièvre, German Biber, dialectal Swedish bjur. Non-Germanic cognates include Welsh befer, Latin fiber, Lithuanian bẽbras, Russian бобр (bobr), Avestan 𐬠𐬀𐬎𐬎𐬭𐬀 (bauura), and Sanskrit बभ्रु (bábhru, “mongoose; ichneumon”).
