The name Reine is not pronounced rain it is pronounced ray-nuh. It is similar to the Spanish Reina which also means queen. The name Reine is French and means queen.
My name is Reine. It is pronounced rainy, like the weather. It was my father's mother's maiden name. I have heard fourteen different pronunciations of it, from the reasonable like Renee and Rayne to the absurd like Reina and Reena.
