Questions & Answers about Los libros nuevos son buenos, y los libros viejos son malos.
Why are the adjectives nuevos and viejos placed after the word libros?
In Spanish, descriptive adjectives (words that describe things, like 'new' or 'old') usually come after the noun they describe. So instead of saying 'the new books', you say los libros nuevos (the books new).
Why do all the describing words (nuevos, buenos, viejos, malos) end in -os?
Adjectives must match the gender and number of the noun they describe. Because libros is a masculine plural noun, all the adjectives describing the books must also take their masculine plural form, ending in -os.
How would this sentence change if we were talking about magazines (las revistas) instead of books?
