Here are some examples:
* Onde você mora? (Where do you live?)
* Onde você está? (Where are you?)
* Onde está o banheiro? (Where is the bathroom?)
However, there are other ways to say "where" depending on the context:
* Para onde (Where to) - used when asking about a destination.
* De onde (From where) - used when asking about the origin of something.
* Aonde (Where to) - used in some regions of Brazil, especially in informal speech.
It's important to note that "aonde" is not considered standard Portuguese and may sound odd to some speakers.
