Plural of Nouns in Spanish – Rules, Examples and Practice

Spanish Plural of Nouns

Welcome to our grammar lesson about the Plural of Nouns in Spanish.

Forming the plural of any noun in Spanish is easy, with clear rules and not many exceptions. 

In this lesson, we begin by dividing nouns into 2 groups: nouns ending in a vowel, and those ending in a consonant. We will study how to form the plural of nouns in each group.

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 their plural just 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 freely to form the plural by adding -s or -es. Both ways are valid:

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

… except a couple of cases for which only the ending in -s is valid. The most frequent are:

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

Plural of nouns ending in a consonant

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

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


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

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


3. Most nouns ending in “s” or “x” don’t change in plural:

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

… except monosyllables, and also words which sound stressed on their last syllable, which add -es:

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


4. Nouns introduced from other languages usually add only -s, even if they end in consonant:

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