The Plural of Nouns in Spanish – Rules, Examples and Practice

Forming the plural of nouns in Spanish is easy, with clear rules and few exceptions. 

This lesson will teach you how to form the plural of nouns, depending on whether they end in a vowel or a consonant.

At the end you’ll find a Quiz and an Exercise for practice.

Plural of nouns ending in a vowel

1. Almost all nouns ending in a vowel form the plural simply by adding -s:

  • la casa → las casas
  • el perro → los perros

2. For most nouns ending in “-í” or “-ú” (with an accent mark), we can choose to add -s or -es. Both ways are valid:

  • el tabú → los tabús / los tabúes
  • el bisturí → los bisturís / los bisturíes

… except a couple of cases where only -s is valid:

  • el champú → los champús
  • el menú → los menús

Plural of nouns ending in a consonant

1. In general, nouns ending in a consonant form the plural by adding -es:

  • el árbol → los árboles
  • la verdad → las verdades
  • el rey → los reyes

2. Nouns ending in “-z” form the plural by changing the “-z” to -ces :

  • la cruz → las cruces
  • la actriz → las actrices

3. Most nouns ending in “-s” or “-x” stay the same in plural:

  • la crisis → las crisis
  • el tórax → los tórax
  • el lunes → los lunes

… except monosyllables, and also nouns which a stressed last syllable. These types of words add -es:

  • el mes → los meses
  • el autobús → los autobuses
  • el país → los países

4. Nouns recently introduced from other languages usually add only -s, even the ones that end in a consonant:

  • el cómic → los cómics
  • el iceberg → los icebergs
  • el chip → los chips
