Gracious
Gianne is a feminine variation of Gian, which is a short form of Giovanni, the Italian equivalent of John. It ultimately derives from the Hebrew name Yochanan, signifying that God has been gracious. While rare in the United States, it offers a sophisticated alternative to more common names like Gianna or Jane.
