REAL: From the name of the city in Georgia, savanna(h) is a word that comes from zabana, which in the language of the Native American tribe the Taino, means "grassy plain." It was first used as a girls' name in the 19th century, but didn't become popular until the late 20th century, possibly influenced by the 1980 movie Savannah Smiles.
