The story of Zosia
Hagia Sophia was built by Justinian in 537 and dedicated to the Wisdom of God, not to a woman — which surprises most visitors. Sophia became a personal name in the eastern church and spread west. Polish gives Zofia, with Zosia as the universal household form, and it has been among the most-used Polish women's names for centuries. It reaches American records with Polish families.
Meaning
wisdom
From Greek sophia, wisdom; the word gives philosophy, the love of wisdom, and names the great church in Constantinople, Hagia Sophia, which is dedicated to Holy Wisdom rather than to a saint of that name.

The Miryam test
Every popular name lives one long story — a climb, a peak, a slow settling back. Zosia's later chapters haven't been written yet, so we borrowed them: Miryam climbed just as high around 1994, and its whole arc is on record. Line the two peaks up, and Miryam's path sketches the road Zosia is walking now.

The trade-off
- A settled Greek meaning that is one of the great words of European thought.
- The initial Z keeps it distinct on any list.
- Five letters and two syllables, quick to write.
- English readers say ZO-see-ah, which is wrong on the middle consonant.
- It reads as a diminutive to Polish speakers, which may matter on a document.
- Zofia and Sophia are both the fuller forms and look quite different.
