Niina is a beautiful Finnish variation of Nina, though it's also used in Estonia and other Baltic regions. The doubled 'i' creates a distinctive spelling while maintaining the same pronunciation as Nina in most cases. With roots in multiple languages, Niina carries various meanings including 'grace' from its Spanish connections and 'strong' or 'mighty' from its Slavic origins. In Nordic countries, the name has been consistently popular since the mid-20th century, appreciated for its simple elegance and international appeal. Niina strikes a perfect balance between familiarity and uniqueness, offering a slightly uncommon spelling of a recognized name.
