Articles and nouns both have plural forms. See the table below for the plural forms of the articles.
| Singular | el | la | un | una |
| Plural | los | las | unos | unas |
If a noun ends in a vowel we add -s to make it plural.
| el libro (the book) | los libros (the books) |
| un libro (a book) | unos libros (some books) |
If a noun ends in a consonant we add -es to make it plural.
| la ciudad (the city) | las ciudades (the cities) |
| una ciudad (a city) | unas ciudades (some cities) |
There are actually some exceptions to the -es rule, but you will learn them in a later lesson.
