"New York is not in California."
Translation:Novum Eboracum in California non est.
Yes, the verb tends to go at the end. However, word order is much more flexible than English and the verb can be placed almost anywhere (usually for emphasis).
The only verb that is quite often seen in other positions is esse (to be), here used as est. It is quite common for some ancient Latin authors to use this more like how verbs are used in many modern Romance languages and English, somewhere in between the subject and the 'direct object'.
Novi Eboraci is in the locative case which is only used with cities/towns, small islands, and I think three other nouns including domus. It is used the same as in California.
We cannot use the locative case since California is not a city in this context. We can use it for New York City however.
There are only three ways to write New York: Novum Eborācum (nominative, accusative, vocative), Novī Eborācī (genitive, locative), and Novō Eborācō (dative, ablative). Each is used in different ways.
They will likely add more cities when the course is out of beta and the next tree get released.
