Оказывается изначально Толкиен назвал Беорна Medwed, но чёт передумал :)
In early manuscripts of
The Hobbit, the name of the character that would become Beorn is Medwed. Medwed's ability to change shape to a bear was due to an enchantment, perhaps of his own.
[10] The similarity between Medwed and
Medved, the Russian word for "bear", is striking, but it is ultimately unknown if Tolkien had this in mind.
