== 他の神々との習合と影響 ==
サルゴンとその後継者の時代にはイナンナとイシュタルが完全に融合していたことに加え<ref>Asher-Greve, Westenholz, 2013, p62</ref>、程度の差こそあれ、多くの神々<ref>Asher-Greve, Westenholz, 2013, p109</ref>と習合していた。最も古い習合の賛美歌はイナンナに捧げられたものであり<ref>Asher-Greve, Westenholz, 2013, p48</ref>、初期王朝時代のものとされている<ref>Asher-Greve, Westenholz, 2013, p100</ref>。古代の書記によって編纂された多くの神名帳には、同様の女神を列挙した「イナンナ・グループ」の項目があり<ref>Behrens, Klein, 1998, p345</ref>、『アン=アヌム』(全7枚)のタブレットIVは、その内容のほとんどがイシュタルの同等者の名前、称号、様々な従者であることから「イシュタルのタブレット」として知られている<ref>Litke, 1998, p148</ref>。 In addition to the full conflation of Inanna and Ishtar during the reign of Sargon and his successors,{{sfn|Asher-Greve|Westenholz|2013|p=62}} she was [[Religious syncretism|syncretised]] with a large number of deities{{sfn|Asher-Greve|Westenholz|2013|p=109}} to a varying degree. The oldest known syncretic hymn is dedicated to Inanna,{{sfn|Asher-Greve|Westenholz|2013|p=48}} and has been dated to the [[Early Dynastic Period (Mesopotamia)|Early Dynastic period]].{{sfn|Asher-Greve|Westenholz|2013|p=100}} Many god lists compiled by ancient scribes contained entire "Inanna group" sections enumerating similar goddesses,{{sfn|Behrens|Klein|1998|p=345}} and tablet IV of the monumental god list ''An-Anum'' (7 tablets total) is known as the "Ishtar tablet" due to most of its contents being the names of Ishtar's equivalents, her titles and various attendants.{{sfn|Litke|1998|p=148}} Some modern researchers use the term ''Ishtar-type'' to define specific figures of this variety.{{sfn|Beckman|1999|p=26}}{{sfn|Beckman|2002|p=37}} Some texts contained references to "all the Ishtars" of a given area.{{sfn|Beckman|1998|p=4}}
In later periods Ishtar's name was sometimes used as a generic term ("goddess") in Babylonia, while a logographic writing of Inanna was used to spell the title ''Bēltu'', leading to further conflations.{{sfn|Asher-Greve|Westenholz|2013|p=110-111}} A possible example of such use of the name is also known from [[Elam]], as a single Elamite inscription written in Akkadian refers to "[[Manzat (goddess)|Manzat]]-Ishtar," which might in this context mean "the goddess Manzat."{{sfn|Potts|2010|p=487}}
