Gracious queen or peaceful song
Reianna is a modern American blend, likely combining the prefix 'Rei' (from the Japanese word for 'gratitude' or 'lovely' or the Latin 'Regina' for 'queen') with the classic suffix 'Anna'. It is often chosen for its melodic sound and its connection to the traditional meaning of Anna, which is 'grace'.
