Royal names tend to carry directly. Regina and Rex are Latin for queen and king. Malik and Malika are Arabic for the same. Celtic traditions give Rian (little king) and Ciara (a queen's name). The theme travels across every language of rule.
Direct versus suggested
A name like Rex or Regina wears the meaning openly. Names like Eric (ever-ruler) or Henry (home-ruler) carry it quietly, embedded in the etymology. Some parents prefer the direct, others prefer the coded.
