Fionna

Fionna is an alternate spelling of Fiona, a name with Scottish Gaelic origins meaning "fair, white, or beautiful." While Fiona emerged as an Anglicization of the Gaelic word "fionn" (fair), this variant spelling with a doubled 'n' adds a distinctive touch to the classic name. The name gained international recognition through James Macpherson's 18th-century Ossian poems, though it didn't become widely used until the 20th century. Fionna offers the same lilting, feminine sound as its more common counterpart while providing visual uniqueness. The name evokes images of Celtic heritage, natural beauty, and gentle strength. Though less common than the standard spelling, Fionna appeals to parents seeking a name with Scottish roots and a slightly unconventional spelling.
