Anu

Anu has two distinct origins. As a feminine name used in Finnish and Estonian, it is a short form of Anna, which itself derives from the Hebrew Channah, meaning grace or favour. As a masculine name in ancient Mesopotamian tradition, Anu was the Sumerian and Akkadian sky god, whose name derives from a Semitic root meaning sky or heaven; he was regarded as the father of the gods and ruler of the uppermost heavens. Related forms include Anna, Anne, and Annu.
