Names That Mean Daring

Some sources give Thorin as a variation of the thunder god name Thor, equivalent to Thoren, while others says it comes from the verb að þora, meaning "to dare." This is a dwarf's name that first appeared in the thirteenth century mythology compilation Prose Edda, which, along with the Poetic Edda, represents nearly all of pagan Scandinavian mythology. Tolkien later used the name for character Thorin II Oakenshield of The Hobbit.

Actress Sigourney -- born Susan -- Weaver made this unusual name (which she found in The Great Gatsby) famous, if not popular.

Beren is a Noldorin name created by J. R. R. Tolkien for his fantasy universe. A great hero in the books, Beren is notable for his love story with Luthien — so notable that Beren and Luthien are the names on the gravestone of Tolkien and his wife, Edith.

Nanna is a name from Norse mythology that is among the Top 30 names in contemporary Denmark. Popular in Norway in the 19th century, Nanna may also be considered a short form of a range of names, from Anna to Johanna to Marianne. As widespread as it is in Scandinavia, though, it's hard to imagine Nanna making a mark as a girl's name in modern day America, given its use as a name for grandmothers.

Nenna is the name of the heroine of Penelope Fitzgerald's novel Offshore, but it's also sparingly used in Scandinavia as a variant of the name Nanna. Nanna is a diminutive of various names, including Anna, Johanna and Marianne, but it's also a name in its own right, possibly meaning "daring".
