Sofiia is a Slavic spelling of Sophia, from Greek sophia meaning "wisdom."
Sofiia is the Ukrainian spelling of one of history's most enduringly beloved names: Sophia, from the ancient Greek σοφία (*sophía*), meaning "wisdom." The Greek root is among the most philosophically laden words in Western intellectual history — Plato's dialogues circle it constantly, the Stoics elevated it as a cardinal virtue, and early Christian theologians made *Sophia* a name for divine wisdom itself, personified as a feminine figure in both Gnostic texts and the Hebrew Book of Proverbs.
The Hagia Sophia — *Holy Wisdom* — built by Justinian in Constantinople in 537 CE, remains one of the architectural wonders of the world. The Ukrainian double-*i* spelling (*Sofiia*) faithfully represents how the name sounds in Ukrainian (Софія), where it has been a common and beloved feminine name for centuries, borne by noblewomen, saints, and ordinary families alike. This orthographic choice connects the bearer explicitly to Slavic heritage at a moment when Ukrainian cultural identity carries particular historical resonance. The name has ranked among the most popular girls' names across Europe and the Americas in the twenty-first century in its various spellings — Sofia, Sophie, Sophia — yet the Sofiia form remains distinctly Eastern European, a small flag of origin planted in a name otherwise shared by the world.
