Spanish feminine form of Isidore, from Greek 'Isis' + 'doron' meaning gift of Isis.
Isidra is the feminine form of Isidore, from the Greek *Isídōros* — a compound of *Isis*, the great Egyptian goddess of magic and motherhood, and *dōron*, meaning "gift." The name therefore carries the remarkable meaning "gift of Isis," making it one of the few names in common Western use that directly honors an Egyptian deity. This syncretic origin reflects the deep cultural exchange of the Hellenistic and Roman Mediterranean, when Isis-worship spread widely through the empire and her name entered Greek and Latin naming conventions.
The masculine Isidore was borne by Saint Isidore of Seville, the seventh-century scholar whose encyclopedic *Etymologiae* helped transmit classical knowledge through the early medieval period — making him a patron saint of the internet in modern times. The feminine Isidra flourished particularly in Spanish-speaking cultures, where it remained a recognized if quietly dignified name through the centuries, most at home in rural Catholic communities where saint's names carried practical as well as spiritual weight. Isidra today is genuinely uncommon, overlooked even among enthusiasts of vintage Spanish names.
Yet it possesses a musicality — the soft sibilant opening, the rolling *r*, the open final vowel — that sits beautifully in the mouth. For those seeking a name with ancient roots and layered meaning, Isidra offers a path back to the crossroads of Egypt, Greece, and Rome.
