* Tu is the informal "you," used for:
* Friends
* Family
* Children
* People you know well
* Sometimes, strangers in casual situations
* Vous is the formal "you," used for:
* People you don't know well
* People in authority (teachers, bosses, etc.)
* Strangers
* Showing respect
* When addressing a group of people
It's important to note that tu is only used with singular subjects. If you are addressing multiple people, you always use vous.
Here are some examples:
* Tu es mon ami. (You are my friend.)
* Vous êtes professeur. (You are a teacher.)
* Tu peux me passer le sel? (Can you pass me the salt?)
* Vous pouvez me dire où est la gare? (Can you tell me where the train station is?)
Remember, choosing between tu and vous depends on the context and your relationship with the person you are talking to.
