Geshtinanna combines the Sumerian geshtin (grapevine) and anna (of heaven). The Sumerian goddess of dream interpretation, poetry, and writing — sister of Dumuzi (Tammuz). When her brother was carried off to the Underworld in Inanna's stead, Geshtinanna volunteered to spend half each year there in his place — establishing the cycle of the seasons.
Featured in Inanna's Descent and the Dumuzi cycle.
Geshtinanna does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Geshtinanna reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
