* '''[[アスタルト]]''': マリやエブラのような都市では、東セム語と西セム語の名前(イシュタルとアシュタルト)は基本的に互換性があるとみなされていた<ref>Smith, 2014, p35</ref>。しかし、西洋の女神はメソポタミアのイシュタルのような幽体離脱の性格を持っていないことが明らかである<ref>Smith, 2014, p36</ref>。ウガリット語の神々のリストと儀式のテキストは、地元の[[アスタルト]]をイシュタルとフルリのイシャラの両方と同一視している<ref>Smith, 2014, p39, 74-75</ref>。
* '''[[イシャラ]]''':イシュタルとの関連から<ref>Asher-Greve, Westenholz, 2013, p134</ref>、シリアの女神イシャラはメソポタミアにおけるイシュタル(およびナナヤ)と同様に「愛の女性」としてみなされるようになった<ref>Murat, 2009, p176</ref><ref>Wiggermann, 2010, p417</ref>。しかし、フルリ・ヒッタイトの文献では、イシャラは代わりに冥界の女神アラーニと結び付けられ、さらに誓いの女神として機能した<ref>Murat, 2009, p176</ref><ref>Taracha, 2009, p124, 128</ref>。
* '''[[ナナヤ]]''':というのも、アッシリア学者のフランス・ウィッガーマンによれば、ナナヤの名前はもともとイナンナの呼称であった(おそらく「私のイナンナ!」という呼びかけの役割を果たした)ため、イナンナと非常に密接な関係にある女神であった<ref>Wiggermann, 2010, p417</ref>。ナナヤはエロティックな恋愛に関連していたが、やがて戦争的な側面も持つようになる(「ナナヤ・ユルサバ」)<ref>Asher-Greve, Westenholz, 2013, p282</ref>。
* '''[[Nanaya]]''': a goddess uniquely closely linked to Inanna, as according to assyriologist Frans Wiggermann her name was originally an epithet of Inanna (possibly serving as an appellative, "My Inanna!"). Nanaya was associated with erotic love, but she eventually developed a warlike aspect of her own too ("Nanaya Euršaba").{{sfn|Asher-Greve|Westenholz|2013|p=282}} In [[Larsa]] Inanna's functions were effectively split between three separate figures and she was worshiped as part of a trinity consisting out of herself, Nanaya (as a love goddess) and [[Ninsianna]] (as an astral goddess).{{sfn|Asher-Greve|Westenholz|2013|p=92}} Inanna/Ishtar and Nanaya were often accidentally or intentionally conflated in poetry.{{sfn|Asher-Greve|Westenholz|2013|p=116-117; 120}}
* '''[[Ninegal]]''': while she was initially an independent figure, starting with Old Babylonian period in some texts "Ninegal" is used as a title of Inanna, and in god lists she was a part of the "Inanna group" usually alongside [[Ninsianna]].{{sfn|Behrens|Klein|1998|p=343-345}} An example of the usage of "Ninegal" as an epithet can be found in the text designated as [https://etcsl.orinst.ox.ac.uk/section4/tr4074.htm Hymn to Inana as Ninegala (Inana D)] in the [[Electronic Text Corpus of Sumerian Literature|ETCSL]].
* '''[[Ninisina]]''': a special case of syncretism was that between the medicine goddess Ninisina and Inanna, which occurred for political reasons.{{sfn|Asher-Greve|Westenholz|2013|p=86}} Isin at one point lost control over [[Uruk]] and identification of its tutelary goddess with Inanna (complete with assigning a similar warlike character to her), who served as a source of royal power, was likely meant to serve as a theological solution of this problem.{{sfn|Asher-Greve|Westenholz|2013|p=86}} As a result, in a number of sources Ninisina was regarded as analogous to similarly named Ninsianna, treated as a manifestation of Inanna.{{sfn|Asher-Greve|Westenholz|2013|p=86}} It is also possible that a ceremony of "sacred marriage" between Ninisina and the king of Isin had been performed as a result.{{sfn|Asher-Greve|Westenholz|2013|p=270}}
