The etymology of the
theonym Aruru (
dA-ru-ru, 𒀭𒀀𒊒𒊒) is considered either uncertain or unknown. A connection with
Sumerian a-ru or
a-ri, which can be translated as "the one who lets the seed flow," has been deemed implausible by Manfred Krebernik, as this term is only used in this sense to refer to men.
Thorkild Jacobsen initially suggested the explanation "the germ loosener," though he eventually abandoned it in favor of translating the name as "outpour of water," or implicitly "outpour of amniotic fluid," which is now considered a mistranslation, as the homophone
arūru means "outlet of a canal," not "outflow."
Gonzalo Rubio states that like other Mesopotamian theonyms of similar structure, such as
Zababa,
Alala,
Belili,
Bunene or
Kubaba, Aruru's name likely did not originate in Sumerian or any of the
Semitic languages, though he also notes theories classifying them as examples of words from a hypothetical
substrate language referred to as "
proto-Euphratean" in old scholarship are now viewed critically in
Assyriology.
Jeremy Black stated that a "pre-Sumerian" origin of Aruru's name cannot be ruled out, though caution is necessary, as she is not attested before the
Third Dynasty of Ur. It has been suggested that the theonyms d, attested in a god list from
Abu Salabikh, and d4-6, referring to
Sarpanit, might be etymologically related to Aruru's name. Julia M. Asher-Greve states that a variant form of the name prefixed with the sign NIN (cuneiform)|, "mistress," is also attested, which according to her is analogous to the interchange between the forms
Azimua and Nin-Azimua. However, according to
Antoine Cavigneaux and
Manfred Krebernik, in the god list
An = Anum the name Nin-Aruru designates a minor goddess from the court of
Ninhursag, designated as one of her six
gud-balaĝ, literally "bull lyres." Krebernik treats her as a separate servant deity. The oldest known sources associate Aruru with vegetation, but do not portray her as a goddess of birth or as a
creator deity. Specific plants mentioned in compositions dedicated to her include
poplar,
date palm,
cedar,
Prosopis and the unidentified
teme and
marmaḫ. She was also portrayed as a powerful and violent deity whose behavior was poetically compared to that of a bull or a viper. While she could be referred to as
ama, according to Jeremy Black despite its literal meaning this term does not necessarily denote her as a mother, and can also be translated as "venerable woman" or simply "female."
Julia M. Asher-Greve, in her analysis of the use of epithets "mother" and "father" to refer to Mesopotamian deities, states that they also could be used to describe to a given deity's position of authority. Black concluded that it would be inaccurate to refer to Aruru understood as a distinct deity as a
mother goddess, as the only sources which describe her directly as a mother of mankind or other gods also syncretise her with other goddesses. ==Associations with other deities==
