Strong and courageous
Andera is a rare feminine variant of Andrew or Anders, ultimately derived from the Greek word 'aner' meaning man. While significantly less common than Andrea, it carries the same etymological weight of bravery and strength. In some contexts, it is also viewed as a feminine form of the Scandinavian name Anders.
