Questions & Answers about Queste curiosità sono molto interessanti.

How do we know curiosità is plural in this sentence since the word doesn't change?

Nouns that end in an accented vowel, like curiosità, are invariable, meaning their spelling doesn't change in the plural. We know it is plural here because the words around it must agree with it: the plural demonstrative Queste, the plural verb sono, and the plural adjective interessanti.

Why do we use Queste instead of Questi?

Most nouns ending in -tà are feminine, such as la curiosità. Since it is plural in this sentence, we need the feminine plural demonstrative adjective Queste (these). If it were a masculine plural noun, we would use Questi.

Why doesn't molto change to molte to match the feminine plural noun?

In this sentence, molto is an adverb meaning very, modifying the adjective interessanti. Adverbs are invariable and never change their endings. If it were an adjective meaning many and directly described the noun, it would change to molte.

Curiosità is feminine, so why does interessanti end in -i instead of -e?
