Because I've completed the Italian module I sometimes dip into the Latin module on Duolingo, which is basic but fun, and I'm delighted that they've decided that the Latin for "New York" is Novi Eboraci. That's literally new "Eboracum", which is what the Romans called the original York in England. It's totally rational and also super hilarious somehow.
[ID: A screengrab of Duolingo's latin module; a character is pointing at their own speech bubble, which reads "Ea Novi Eboraci Studet"; I have translated this correctly below as "She studies in New York."]
