God is gracious
Giann is a rare variant of Gian, which is the Italian short form of Giovanni. It ultimately derives from the Hebrew name Yochanan, meaning 'Yahweh is gracious.' While less common than the single-n spelling, it retains the same classic European roots.
About 20 boys were named Giann in 2025.
