"You live in Boston."

Translation: Bostoniae habitas.

I could be wrong, but Bostoniae means either of Boston, (Gen.)to or for Boston (Dat.), or Bostons (N.Pl.). So, wouldnt all of these be incorrect?

[Moopish]

Since Boston is a city we are using the locative case here, which is also Bostoniae.

Thank you. I was confused about it.

[PERCE_NEIGE]

You can eliminate the plural "Bostons" for a city (unless you write science fiction books with alternative dimensions).

As the verb is "habitas", it's impossible to have a genitive here: there is no noun.
Of boston for who?
Same :"for Boston" with "to live"? To live for Boston? I have no idea how to say this in Latin (someone will tell us), but, as you have "habitare" you wait for a place, and often a locative (if it's a city) or an ablative with a preposition (if it's a country).

The original Boston still exists in England.

I put "tu" at the beginning and it marked me wrong

[Moopish]

Did you use habitas or habitatis? If you used the latter, that would not be correct as that is a plural form of the verb. If you used the former then report it next time it happens to you.
