Learn Italian: Voglio provare parecchi fondotinta. - I want to try quite a few foundations.

It sits right in the middle! Parecchi means "several" or "quite a few." It expresses a quantity that is more than just a few (alcuni) but usually not quite as extreme as "many" or "a lot" (molti).

Why do we use the masculine plural parecchi when fondotinta ends in -a?

Even though it ends in -a, fondotinta (foundation makeup) is a masculine noun. Because the speaker wants to try several foundations, the noun is plural here, so the adjective must agree and take the masculine plural form parecchi.

If it's plural, why doesn't the noun change to fondotinte or fondotinti?

Fondotinta is a compound noun made from fondo (base/bottom) and tinta (color/dye). Nouns formed this way are often invariable, meaning their spelling stays exactly the same in singular and plural. You rely on context or modifying words—like parecchi—to know it's plural.

Just to review, do I ever need a preposition like di or a between voglio and provare?
