I believe the name
Reina is a Yiddish name prn REH-ee-nah meaning "clean" or a French name prn RAIN-nah meaning rain. Maybe to be sure you get the correct prn and meaning you should spell it
Raina or
Rayna which would also be a English name meaning rain. Just a suggestion.
I think it is a beautiful name either way
Reina or
Raina and I even kind of like REH-ee-nah if someone were to prn it that way.
