Questions & Answers about Os carros azuis são rápidos.
Why is the plural of the color blue azuis?
In Portuguese, words that end in -l, like the singular azul, usually form their plural by dropping the -l and adding -is. That is how we get azuis to describe the plural carros.
Rápidos ends in -os to match the masculine carros. Why doesn't azuis change for gender too?
Adjectives that end in a consonant, like azul, are usually gender-neutral, meaning they are exactly the same for both masculine and feminine nouns. When we make it plural by changing it to azuis, it is still gender-neutral, so it doesn't need an -os ending.
Why does this sentence use são instead of estão for "are"?
Why is the word order carros azuis instead of azuis carros?
In Portuguese, adjectives that describe literal facts, like colors or shapes, almost always come right after the noun they describe. So "blue cars" becomes "cars blue" (carros azuis).
