Interrogative adjectives indicate a quality or indefinite quantity and come with specific nouns. The most common forms are che (what? what kind of?), quale (which?), and quanto (how much? how many?). For example:

Quali parole ricordi? (Which words do you remember?)

Che libri leggete? (What books do you read?)

Quante ragazze vengono? (How many girls are coming?)

Che ora è? (What time is it?)

Quanto pane vuoi? (How much bread do you want?)
