In all the world, Silvera (Silvera , Сильвера ) is quite a rare primarily feminine, but very seldom boy's forename. The forename Silvera is characteristic of Latin America and the Caribbean, particularly Paraguay, where it is quite a rare female name, Uruguay, where it is a rare epicene name, and Brazil, where it is a rare feminine name. Not in comparison with a country's population, it is the most numerous in Brazil, Indonesia, and Paraguay. More prevalently, Silvera is the last name as well as the forename.
Silvera is also a name for the fictitious and mythical characters: Silvera , the operatic character in the opera Zanaida.
