Learn Portuguese (Portugal): Os sapatos azuis são lindos.

In Portuguese, adjectives must match the noun they describe. Since sapatos (shoes) is plural, the adjective azul (blue) must also be plural. For words ending in the consonant -l, you form the plural by dropping the -l and adding -is, making it azuis.

Why does azuis come after sapatos?

Unlike in English, where we say 'blue shoes', descriptive adjectives like colors in Portuguese almost always come after the noun they describe. So, the sentence structure translates literally as 'shoes blue' (sapatos azuis).

Why does lindos end in -os?

Lindos (beautiful) describes the shoes. Because sapatos is a masculine plural noun, the adjective must also take the masculine plural ending -os. If we were describing a feminine plural noun like roupas (clothes), we would use lindas instead.

Why use são instead of estão?
