Questions & Answers about La cubierta es nueva.

Why is it la cubierta and not el cubierta?

Because cubierta is a feminine noun, so it takes the feminine singular article la.

In Spanish, articles have to match the noun’s gender:

• el = masculine singular
• la = feminine singular

So:

• la cubierta
• not el cubierta

This is grammatical gender, so it does not necessarily mean anything is biologically female.

Why is it nueva and not nuevo?

Because adjectives in Spanish usually agree with the noun they describe in gender and number.

Here:

• cubierta is feminine singular
• so the adjective must also be feminine singular: nueva

Compare:

• el libro nuevo
• la casa nueva
• las casas nuevas

So La cubierta es nueva is correct because both cubierta and nueva are feminine singular.

Why do we use es here and not está?
