Porque yo vivo in Pittsburgh
Same as in English.
Pittsburgh. The spelling does not change in Spanish when your talking about a city. Sometimes, however, it will depending if the city or place is an actual English word. For example, Saint Paul (Minnesota) is San Pablo in Spanish.
You can say "¿Dónde vives?"
Yo vivo en Newcastle would the best way to say "I live in Newcastle" in Spanish.
Yo vivo - I live where- donde
"Yo soy de" and then where you live.
Donde vives?
You say: Vivo en Bakersfield.
I'm assuming you are asking how to say that in Spanish, as 'you live in Illinois' is in English, not Spanish. it's "vives in Illinois."
The Spanish translation for "Do you want to live here?" is "¿Quieres vivir aqui?.
The best way to say "I live in" would be "Yo vivo en".
Para siempre.
