The plural forms of nouns and articles

Articles and nouns both have plural forms. See the table below for the plural forms of the articles.

Pluralloslasunosunas

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.
