Learn Portuguese (Portugal): O sofá verde é novo.

Most Portuguese words ending with the letter a are feminine, but sofá is an exception. It is a masculine noun, which is why it is paired with o instead of a.

Why does the word verde come after sofá?

In Portuguese, words that describe things (adjectives) usually come right after the noun they are describing. Instead of saying green sofa, you literally say sofa green (sofá verde).

Since sofá is masculine, why doesn't verde end in o just like novo does?

Adjectives that end in the letter e, like verde, are neutral and do not change. They are used for both masculine and feminine words. The word novo does change for gender, so it takes the masculine o ending to match sofá.

Why do we use é here instead of está for the word is?

We use é (from the verb ser) for lasting qualities or defining facts. Being new is considered an essential characteristic of the object itself, rather than a temporary state.
