"Variant of Regina"
The name Reginae is commonly a female name from the "Latin" origin.
Reginae is the Latin genitive singular of regina, the Latin word for queen, and the same form also serves as the nominative plural. It entered United States birth records in 1991, which places it with modern elaborated spellings of the given name Regina rather than with older established use of that name.
Regina means "Queen".
The pronunciation of Reginae is reh-JEE-nay.
