Joasia

Joasia is a Polish feminine diminutive of Joanna, which itself derives from the Hebrew name Yohannah, meaning God is gracious. It developed as an affectionate pet form used in everyday speech and within families, reflecting the Polish tradition of forming diminutives from longer given names. The name shares its ultimate Hebrew root with Joan, Jane, Jean, and Hanna, all of which spread widely across Europe through the influence of early Christianity.
