"Do you live in California?"
Translation:Habitasne in California?
As Escargotville mentions below, it's actually detailed in the Tips and Notes for the NEXT skill Places.
From the tips and notes for the next skill "Places": The locative case is a special case which indicates a location used for cities. Some general rules: -a (first declension) becomes -ae -us and -um (second declension) become -i
Other locations will generally get a preposition (in + ablative, we will deal with the ablative later in the course).
Yeah like before this it said "Habitasne Romae" so for my answer I put "Habitsne California" and it said I was wrong :/
It says in the notes that the ending change is for cities, so since California is a state I assume that's why Californiae doesn't work
