Questions & Answers about El libro es malo.

Why do we say El libro (masculine article) instead of La libro?

In Spanish, nouns have gender. Libro is a masculine noun, so it takes the masculine article el and the masculine form of the adjective (malo instead of mala).

Why do we use es instead of está?

Ser (here, es) is used for more permanent or inherent characteristics. Saying El libro es malo implies that, as a characteristic, the book is bad or of poor quality, rather than only temporarily bad or in poor condition (which would be expressed with está).

Why is the adjective malo used and placed after the noun?

In Spanish, adjectives typically go after the noun they describe, especially if they are describing inherent qualities. Malo is the masculine form of the adjective bad, so we say libro malo (bad book) rather than libro mala.

Can malo ever change to something else when placed before the noun?

Yes. The adjective malo can become mal when placed directly before a masculine noun (for style or emphasis). For instance, un mal libro (a bad book). But in basic descriptive form following the noun, you use malo.
