Question words practice

Here is how you form "What"

Que is basic word for what in sentences like "what are you doing?" Que fais-tu?
est-ce que is a common way of forming a question (instead of inversion) and means is it that?
to put the 2 together you need to change que to qu'
so Qu'est-ce que Qu'est-ce que tu fais?

If the next word begins with a vowel the that last -e becomes '
Qu'est-ce qu'il y a …? What is there …?

If what goes with a noun then it is quel, quelle, quels, quelles depending on the noun.
eg Quel temps? Quel âge? Quelle heure? Quelle couleur? Quels sont tes passe-temps préférés?

There are notes with examples in the GRAMMAR folder in My Teachig Files
