How to form the plural of Spanish nouns

The plural form of a noun refers to multiple or more than one of something. When a noun is plural the accompanying article is also plural.

In Spanish grammar the plural ending is usually -s or -es and articles also take -s in their plural form. In general, nouns have a singular and a plural form, although this is not always the case: like in English, there are nouns that only exist in the singular (e.g. la saludhealth), and nouns that only exist in the plural (e.g. las faucesjaws).

Nouns ending in a vowel

Nouns that end in a vowel (a, e, i, o, u) usually take the plural ending -s.

Example:
el libro → los librosthe book → the books
la mesa → las mesasthe table → the tables

If the final letter is a stressed í or ú, then we add -es.

Example:
el jabalí → los jabalíesthe wild boar → the wild boars
el bambú → los bambúesthe bamboo → the bamboos

Nouns ending in a consonant

Nouns that end with the consonants -d, -j, -l, -n, and -r take the plural ending -es.

Example:
el ordenador → los ordenadoresthe computer → the computers
el reloj → los relojesthe clock → the clocks

A -z at the end of a word changes to -c before taking -es.

Example:
La cruz → las crucesthe cross → the crosses

Foreign words that end with a consonant form the plural with either -s or -es.

Example:
el club → los clubs/clubesthe club → the clubs

To Note

When the plural is formed by adding -es, the word gains an extra syllable. In order to keep the stress on the correct syllable, it may be necessary to add or remove an accent in some words.

Example:
el examen → los exámenesthe exam – the exams
la institución → las institucionesthe institution – the institutions

Special cases

Nouns that end with -s or -x and have an unstressed final syllable do not take any extra ending in the plural.

Example:
el cactus → los cactusthe cactus – the cacti
el tórax → los tórax the thorax – the thoraxes

However, if the final syllable is stressed, we add -es.

Example:
el autobús → los autobusesthe bus → the buses

Singular or plural?

Most nouns can be used in the singular and in the plural.

Example:
el elefante → los elefantesthe elephant → the elephants
la piscina → las piscinasthe swimming pool → the swimming pools

However, some nouns only exist in the singular.

Example:
el dineromoney
el hambrehunger

While some nouns only exist in the plural.

Example:
las faucesthe jaws
los víveressupplies

There are also nouns that have the same form in singular and plural.

Example:
un miércoles al mesone Wednesday a month
todos los miércoles al mesall Wednesdays in the month

Some nouns that are only plural in English can be singular or plural in Spanish.

Example:
una gafa/unas gafasglasses
una tijeras/unas tijerasscissors
el pantalón/los pantalonestrousers
