Regina (Latin, 'queen'), Rex (Latin, 'king'), Malik (Arabic, 'king'), Malika (Arabic, 'queen'), Sarah (Hebrew, 'princess'), and Basil (Greek, 'kingly') all belong here. The theme is one of the oldest continuous naming traditions.
A royal name is a wish made in an old language. Parents rarely say 'I want my child to be a king' out loud, but a name can carry that hope for them.
