Spanish Plural Nouns: -s, -es and -ces

Spanish plurals often use -s or -es. The ending of the singular helps you choose: libro → libros, hotel → hoteles, lápiz → lápices. Learn these common patterns first, then watch for words such as lunes that stay the same. The article also becomes plural.

Ends in a vowel: add -s

Add -s after an unstressed vowel, or a stressed -á, -é or -ó. Stressed -í and -ú need a separate note below.

Many nouns ending in stressed -í or -ú allow both -s and -es: esquí → esquís / esquíes. Some common words mainly use -s, including menú → menús. Check a dictionary for a new word in this group.

Common consonant endings: add -es

Common nouns ending in -l, -r, -n, -d or -j take -es: hotel → hoteles. For endings in -s, stress matters; see the unchanged words below.

Do not extend this to every consonant ending: robot → robots and cómic → cómics take -s. The familiar word rey has reyes, but not every word ending in -y follows that pattern.

-z changes to -ces

A noun that ends in -z follows the consonant rule, with one spelling change: z becomes c before -es. Spanish does not normally write z before e or i. The sound of the consonant stays the same.

Adjectives do the same: feliz → felices.

When the written accent changes

In the examples below, stress stays on the same syllable. Adding -es changes the number of syllables, so the written accent may disappear or become necessary. Keep the spoken stress and the written accent separate.

A useful habit: nouns in -ción and -sión drop the accent in the plural — estación → estaciones, televisión → televisiones. País → países keeps it.

Words that do not change: el lunes, los lunes

Many singular nouns end in -s. If they have more than one syllable and are not stressed on the last one, they normally stay unchanged in the plural. In the pairs below, the article distinguishes singular from plural.

Words ending in -s usually add -es when they have one syllable or are stressed on the last syllable:

The days from Monday to Friday do not change (el viernes, los viernes). Sábado and domingo end in a vowel, so they are regular: los sábados, los domingos.

Common mistakes

Using -s in hoteles or ciudades. These common endings need -es. Do not copy English hotels into Spanish.

Keeping the z. Before -es, the z is written c.

Adding -es to lunes. A word like lunes, which is not stressed on its last syllable, does not change.

Ignoring written accents. The examples below keep the same spoken stress, but the written accent follows Spanish spelling rules.

Forgetting the article. English “the” never changes, but Spanish el and la do: los, las.
