Learn Romanian: Avem o mașină nouă.

In Romanian, adjectives usually come right after the noun they describe. So instead of saying 'a new car' like in English, you say 'a car new' (o mașină nouă).

Why is the word for 'new' nouă here instead of nou?

Adjectives in Romanian have to match the gender of the noun. The word for car (mașină) is feminine. The basic masculine form of 'new' is nou, but its feminine singular form is nouă.

Wait, doesn't nouă also mean the number nine? How do I tell them apart?

Yes, it does! Nouă is a homonym that means both 'new' (feminine singular) and 'nine'. You can tell them apart by the word order and the noun. If it meant 'nine cars', the number would come before a plural noun: nouă mașini. Here, it comes after a singular noun, so it must be the adjective 'new'.

Where is the word for 'we' in this sentence?

The word for 'we' is noi, but you don't need to say it here. The verb avem specifically means 'we have', so the pronoun is usually dropped unless you want to add special emphasis.
