また、文脈上の痕跡や 楔形文字の学位記の音訳から、最古のシュメール語の名前は少なくとも時にはズーとも発音され、アンズーは主にアッカド語の名前であると主張されている。しかし、両言語には両方の読み方を示す証拠があり、接頭辞𒀭 (''AN'')がしばしば神や単に高い場所を区別するために使われたという事実によって、この問題はさらに混乱している。AN.ZUは単に「天の鷲」を意味するのかもしれない<ref name=alster>Alster, B.

Thorkild Jacobsen proposed that Anzu was an early form of the god [[Abu (god)|Abu]], who was also [[Religious syncretism|syncretized]] by the ancients with [[Ninurta]]/Ningirsu, a god associated with thunderstorms. Abu was referred to as "Father Pasture", illustrating the connection between rainstorms and the fields growing in Spring. According to Jacobsen, this god was originally envisioned as a huge black thundercloud in the shape of an eagle, and was later depicted with a lion's head to connect it to the roar of thunder. Some depictions of Anzu therefore depict the god alongside goats (which, like thunderclouds, were associated with mountains in the ancient Near East) and leafy boughs. The connection between Anzu and Abu is further reinforced by a statue found in the [[Tell Asmar Hoard]] depicting a human figure with large eyes, with an Anzu bird carved on the base. It is likely that this depicts Anzu in his symbolic or earthly form as the Anzu-bird, and in his higher, human-like divine form as Abu. Though some scholars have proposed that the statue actually represents a human worshiper of Anzu, others have pointed out that it does not fit the usual depiction of Sumerian worshipers, but instead matches similar statues of gods in human form with their more abstract form or their symbols carved onto the base.<ref name=jacobsen1989/>

In [[Sumerian religion|Sumerian]] and [[Akkadian literature#Mythology|Akkadian]] mythology, Anzû is a divine storm-bird and the personification of the southern wind and the thunder clouds.<ref>{{cite book |author=Jean Bottéro |title=L'Oriente antico.
