"Blend of Lu and Anna"
The name Luanna is commonly a female name.
Luanna is a compound name formed from Lu, a short form of Louise or Louisa, joined to Anna. It matches a pattern in nineteenth-century American naming in which a clipped first element was attached to a second given name, as in Luella and Louetta. The name first appears in United States birth records in 1888, which is consistent with that pattern rather than with an older inherited name.
The pronunciation of Luanna is loo-AN-uh.
