Athanasiah is Greek in Origin.

Athanasiah is a rare feminine elaboration of Greek Athanasía/Athanasia, from a- “not” + thánatos “death,” meaning “immortal, deathless.” The -iah ending echoes Hebrew name patterns in English but the root is fully Greek; Athanasiah likely arose as an Anglicized, ornamental variant rather than a traditional form.

The name’s history traces to the Christian East: bearers include Saint Athanasia of Aegina (9th century), and the masculine cognate is famed in St. Athanasius of Alexandria. Athanasia remains in use in Greece and Cyprus, with nicknames Nasia and Sia (and Nancy in modern Greek). Cross-language variants include Athanasia/Athanasía (Greek), Atanasia/Atanásia (Iberian and Balkan), Atanasija (Serbian/Macedonian), Atanasiya (Bulgarian), and Afanasiya/Afanasia (Russian). In English-speaking countries Athanasiah appears sporadically from the 19th century onward, chiefly in religious or heritage contexts; today it offers a distinctive, meaning-rich choice conveying endurance and life.
