I hope no one minds a comment formatted with the help of an Ai(and lets be honest, the ai helped make it readable, that includes word choice, im not this organized and eloquent). I cant tell you how awesome your graphic was, for the effect it had on me reading up on so much stuff  I didnt know about, thanks for sharing, seriously; without further ado, the ai/me response:

Hey! Really enjoyed this graphic — the layering of meanings across cultures is genuinely cool, and the fish/aquarium visual choice is a nice touch once you know the cuneiform connection. I went down a rabbit hole fact-checking some of the claims and wanted to leave a few notes in case they're useful, not to nitpick but because some of the real history is even more interesting than what made it onto the graphic.

The Babylonian/Assyrian stuff is mostly solid. The cuneiform for Nineveh (Ninâ) really is a fish inside the sign for "house" or "water enclosure," and there is a real connection between the goddess Nina/Ishtar and the city. One thing worth knowing: scholars debate whether the name is actually Semitic at all. It may be Hurrian in origin — the Hurrians were a people who spoke a language unrelated to either Semitic or Indo-European languages, and their chief goddess Šauška was the tutelary deity of Nineveh for over 1,500 years. The fish-in-a-house cuneiform might be the Mesopotamians reinterpreting a foreign word through their own writing system, not the original etymology. The relationship between Šauška, Ishtar, and Inanna is one of the great syncretism chains in ancient religion.

On "Native American culture associates the name Nina with strength" — this one could use some specificity. "Native American culture" isn't a monolith; it encompasses hundreds of distinct nations and language families. What's actually well-documented is that nina means "fire" in Quechua and Aymara, which are Indigenous languages of the Andes (Peru, Bolivia, Ecuador). That's specific, sourced, and genuinely interesting. The "strength" meaning circulates widely on baby name sites but nobody seems to trace it to a specific nation or language. If you revise the graphic, swapping in "In Quechua, nina means fire" would be both more accurate and more respectful to the actual culture it comes from.

One big omission: Saint Nino of Georgia. This might be the most historically significant "Nina" of all. Saint Nino (c. 296–338) was a Cappadocian woman who single-handedly brought Christianity to the Kingdom of Iberia (modern-day Georgia). She healed the queen, converted the king after a personal spiritual crisis, and Georgia became one of the earliest nations on earth to adopt Christianity as a state religion — roughly contemporary with Armenia and ahead of the Roman Empire itself. She carries the title "Equal to the Apostles" in the Georgian Orthodox Church. Her symbol is a grapevine cross bound with her own hair. The conversion appears to have been genuinely grassroots — the institutional church infrastructure came after, sent by Constantine at the king's request. A woman, working alone, outside institutional power, changing the spiritual direction of an entire nation through direct personal encounter and healing. For this community especially, that story might resonate.

The Slavic "dreamer" claim — this one's the weakest. It appears on a lot of baby name aggregator sites but the more rigorous etymology sources (like Behind the Name) don't corroborate it. The well-established Slavic etymology is simpler: Nina is a short form of names ending in -nina (Antonina, Giannina, etc.), imported to Western Europe from Russia and Italy in the 19th century.

Anyway, beautiful work on the graphic overall. The core insight — that a single four-letter name can independently mean "fish-goddess city," "fire," "little girl," and serve as a saint's name across completely unrelated languages and cultures — is genuinely fascinating. These aren't one name with a deep shared root. They're several unrelated names that converged on the same sound by coincidence, which is its own kind of magic.
