Plural Power-Up: A Simple Guide to Forming the Spanish Plural


Ever find yourself trying to say something like “the houses” in Spanish and getting stuck? While English plural rules are pretty simple, Spanish plural forms can seem a bit tricky at first. But don't worry! Once you learn a few basic principles, you'll find that forming the plural in Spanish is actually one of the easiest parts of Spanish grammar. Let’s break it down into simple, easy-to-understand rules so you can master them in no time.


The Two Main Rules for Regular Nouns

Most Spanish nouns follow one of two simple rules. If you can remember these, you're 90% of the way there.

Rule #1: If a noun ends in a vowel (-a, -e, -i, -o, -u), simply add an -s to the end.

This is the most common rule, and it works for a huge number of words. Remember that the gender of the noun also affects the article that goes with it (Spanish gender is important here too!).

  • la casa (the house) → las casas (the houses)

  • el libro (the book) → los libros (the books)

  • la calle (the street) → las calles (the streets)

  • el coche (the car) → los coches (the cars)

See? It’s just like adding an 's' in English!

Rule #2: If a noun ends in a consonant, add -es to the end.

This rule applies to all nouns that don't end in a vowel. It's the key to knowing how to make Spanish nouns plural when the first rule doesn't apply.

  • el papel (the paper) → los papeles (the papers)

  • la ciudad (the city) → las ciudades (the cities)

  • el árbol (the tree) → los árboles (the trees)

  • la televisión (the television) → las televisiones (the televisions)


The Exceptions: Irregular Nouns and Special Cases

Now that you know the two main Spanish plural rules, let's look at a few special cases. These are the Spanish plural irregular nouns that sometimes trip people up, but once you learn the rules, they're not so tough.

  • Nouns ending in -z: For words ending in 'z', you change the 'z' to a 'c' and then add '-es'.

    • el lápiz (the pencil) → los lápices (the pencils)

    • la voz (the voice) → las voces (the voices)

  • Nouns that are already plural: Some nouns already end in '-s' or '-es' and don't change in the plural. You can tell if they are plural by looking at the article in front of them (el vs. los).

    • el lunes (Monday) → los lunes (Mondays)

    • el paraguas (the umbrella) → los paraguas (the umbrellas)

  • Nouns ending in a stressed vowel with an accent: These nouns can be a bit tricky, but most of them follow a rule. If the stressed vowel is í or ú, you generally add -es.

    • el jabalí (the wild boar) → los jabalíes (the wild boars)
