Learn Italian: Le case italiane sono molto belle. - The Italian houses are very beautiful.

Casa (house) is a feminine noun that ends in -a. To make it plural, the -a changes to -e, becoming case. The singular definite article la also changes to its feminine plural form, le.

Why do italiane and belle both end in -e?

In Italian, adjectives must match the noun they describe in both gender (masculine or feminine) and number (singular or plural). Because case is feminine and plural, the adjectives italiana and bella change their -a endings to -e to match the noun perfectly.

If everything else is feminine and plural, why doesn't molto change to molte?

In this sentence, molto means 'very' and is acting as an adverb describing how beautiful the houses are. Adverbs never change their endings! If molto meant 'many' and was describing a noun (like 'many houses'), then it would act as an adjective and change to match the noun (molte case).

Why is italiane placed after case?
