Question

Can we ask "Tu as quel âge?" or "Vous avez quel âge?" ?

Accepted Answer

Hi Janet,
If you are asking when to use 'tu' or 'vous' you will find this lesson pertinent -
Using Tu and Vous to express three types of you in French (French Subject Pronouns)

Answer

Yes, these are correct as well. And you have also a third option. From most formal to least formal:

1. Quel âge avez-vous? (inversion)

2. Vous avez quel âge?

3. Quel âge vous avez?

You have these three options with most partial questions.

Something to note with "quel âge a...." is, that, if the subject is a noun and not a pronoun, you have to use following form, if you want to use inversion (Option 1):

Quel âge a cette fille? NOT: Quel âge cette fille a-t-elle? Which would be the normal way of handling inversion with partial questions and noun subjects as described here: Inverted questions in the present tense (Le Présent) in French - with names/things/emphasis
