Singular and Plural Nouns in Spanish

This section introduces singular and plural nouns in Spanish and includes tips for students studying foundation and higher tiers. In Spanish, nouns can be singular or plural. Singular nouns refer to one person, thing, or concept, while plural nouns refer to more than one. Understanding how to form the plural of nouns is crucial for sentence construction, as articles and adjectives also change based on number.

Singular Nouns

A singular noun refers to one item, person, or concept.

Examples (Foundation Level):

• el libro (the book)
• la casa (the house)
• el perro (the dog)
• la mesa (the table)
• la chica (the girl)

Plural Nouns

To make a noun plural in Spanish, you generally follow specific rules depending on the ending of the singular noun.

Common Rules for Forming Plural Nouns (Reglas comunes para formar sustantivos plurales):

Nouns ending in a vowel (a, e, i, o, u): Add -s to the singular form.

• Example:el libro (the book) → los libros (the books)
• Example:la casa (the house) → las casas (the houses)

Nouns ending in a consonant (except -z): Add -es to the singular form.

• Example:el profesor (the teacher) → los profesores (the teachers)
• Example:la ciudad (the city) → las ciudades (the cities)

Nouns ending in -z: Change -z to -ces in the plural form.

• Example:el lápiz (the pencil) → los lápices (the pencils)
• Example:la voz (the voice) → las voces (the voices)

Nouns ending in -s or -x in the singular: The plural is the same as the singular form, and only the article changes.

• Example:el análisis (the analysis) → los análisis (the analyses)
• Example:el fax (the fax) → los faxes (the faxes)

Irregular Plurals

Some nouns have irregular plural forms that do not follow the typical rules. These must be memorised.

Examples (Irregular Plurals):

• el hombre (the man) → los hombres (the men)
• la mujer (the woman) → las mujeres (the women)
• el niño (the boy) → los niños (the boys)
• la niña (the girl) → las niñas (the girls)
• el amigo (the friend) → los amigos (the friends)

Nouns with Accents

If a singular noun has an accent on the last syllable, the accent is kept in the plural form.

Examples (Foundation Level):

• el camión (the truck) → los camiones (the trucks)
• la canción (the song) → las canciones (the songs)

Nouns Ending in -e or -ista 

For nouns that end in -e or -ista, the plural form is created by adding -s (there is no change in the vowel or the ending).

Examples (Foundation Level):

• el coche (the car) → los coches (the cars)
• la clase (the class) → las clases (the classes)
• el artista (the artist) → los artistas (the artists)
• la artista (the artist, female) → las artistas (the artists, female)

Gender Agreement with Plural Nouns

When forming the plural of a noun, articles and adjectives must also agree in number and gender.

• Masculine plural article: los (the)
  • Example:los niños felices (the happy boys)
• Feminine plural article: las (the)
  • Example:las chicas inteligentes (the intelligent girls)
• Masculine plural adjective: Generally ends in -os.
  • Example:los perros grandes (the big dogs)
• Feminine plural adjective: Generally ends in -as.
  • Example:las casas grandes (the big houses)

Using Definite and Indefinite Articles with Plural Nouns

Articles must agree in gender and number with the noun.

Definite Articles (Artículos definidos):

• Masculine plural: los (the)
  • Example:los libros (the books)
• Feminine plural: las (the)
  • Example:las mesas (the tables)

Indefinite Articles (Artículos indefinidos):

• Masculine plural: unos (some, a few)
  • Example:unos amigos (some friends)
• Feminine plural: unas (some, a few)
  • Example:unas casas (some houses)

Adjective Agreement with Plural Nouns

Just like articles, adjectives must agree with plural nouns in both gender and number. For plural adjectives, you generally add -s to the adjective if it ends in a vowel, or -es if it ends in a consonant.

Examples (Foundation Level):

• los niños felices (the happy boys)
• las niñas felices (the happy girls)
• los coches rápidos (the fast cars)
• las mesas grandes (the big tables)

Examples (Higher Tier):

• los hombres inteligentes (the intelligent men)
• las mujeres guapas (the beautiful women)
• unos libros interesantes (some interesting books)
• unas ideas fantásticas (some fantastic ideas)

Summary

• In Spanish, nouns can be singular or plural, and the plural form is formed by adding -s or -es, depending on the ending of the noun.
• Nouns ending in a vowel (except -e) usually form the plural by adding -s.
• Nouns ending in a consonant (except -z) form the plural by adding -es.

• Some nouns, like el hombre and la mujer, have irregular plurals that must be memorised.

These rules will help you form and understand singular and plural nouns in Spanish, ensuring that you use the correct form in both writing and speaking.
