In French, the phrase ‘Do you have’ is translated as ‘Avez-vous’ or ‘Tu as’, depending on the level of formality.
‘Avez-vous’ is used in formal situations or when addressing someone you don’t know well. It’s considered polite and is commonly used in questions. For example, you might ask, ‘Avez-vous un stylo?’ (Do you have a pen?)
On the other hand, ‘Tu as’ is used in informal contexts, such as when talking to friends or family. For instance, you could say, ‘Tu as des frères?’ (Do you have any brothers?)
So, when deciding between these two phrases, consider the context and the relationship you have with the person you’re speaking to.
