Beam of light or queenly
Rayonna is a modern American creation, likely blending the English word 'ray' (as in a ray of sunlight) with the popular '-onna' suffix. It may also be interpreted as a feminine elaboration of Raymond, meaning 'wise protector', or influenced by the Latin 'regina' meaning queen.
