Learn Italian: Ci sono alberi vecchi in quella strada. - There are old trees in that street.

Ci sono means "there are" and is used with plural nouns. Since we are talking about multiple trees (alberi), we must use ci sono. If we were talking about just one tree, we would use c'è ("there is").

Why does vecchi come after alberi?

In Italian, most descriptive adjectives like vecchi (old) are placed right after the noun they describe. Notice that it also ends in -i to match the masculine plural noun alberi.

Why is there an 'h' in the word vecchi?

The singular form is vecchio, which has a hard "k" sound. To make it plural, the ending changes to -i. If we just wrote "vecci", the rules of Italian pronunciation would make the "ci" sound soft (like in "cheese"). Adding the h keeps the hard "k" sound in the plural form.

Why do we use in instead of nella before quella strada?
