Pietra

Pietra is the Italian and Portuguese feminine form of the name Peter. The name Peter itself is derived from the Greek word 'petros' (πέτρος), meaning 'rock' or 'stone'. This name gained immense popularity due to Saint Peter, one of the twelve apostles of Jesus Christ, who was originally named Simon but was given the Aramaic name Cephas (meaning 'rock') by Jesus, which was then translated into Greek as Petros.

While Peter became a foundational name in Christianity for males, its feminine forms like Pietra, Petra, and Piera developed in various European languages. Pietra specifically maintains a strong connection to its Latin and Greek roots through its Italian and Portuguese usage, symbolizing steadfastness and strength.
