Indefinite Adjectives in Spanish

This section explains indefinite adjectives in Spanish and includes tips for students studying foundation and higher tiers. Indefinite adjectives are used to describe unspecified or unknown quantities of something or someone. They are similar to English adjectives like "some", "few", "many", and "certain", and they do not refer to a specific or definite item or person. In Spanish, these adjectives must agree with the gender (masculine/feminine) and number (singular/plural) of the noun they modify.

Common Indefinite Adjectives

Here is a list of common indefinite adjectives in Spanish, along with their English meanings. Note that they change depending on the gender and number of the noun they describe.

Agreement of Indefinite Adjectives

Indefinite adjectives in Spanish agree with the gender and number of the noun they modify. This means that they change according to whether the noun is masculine or feminine, and whether it is singular or plural.

Examples:

  • Algún libro (Some book)
    Libro is masculine and singular, so we use algún.
  • Algunos libros (Some books)
    Libros is masculine and plural, so we use algunos.
  • Alguna chica (Some girl)
    Chica is feminine and singular, so we use alguna.
  • Algunas chicas (Some girls)
    Chicas is feminine and plural, so we use algunas.

Special Forms of Indefinite Adjectives

Some indefinite adjectives have special forms that need to be used with specific nouns.

Algún and Ningún:

  • Algún (some, any) and ningún (no, none) are shortened forms of alguno and ninguno, but they are only used before masculine singular nouns.

Examples:

  • Algún día (Some day)
    Día is masculine, so we use algún instead of alguno.
  • Ningún amigo (No friend)
    Amigo is masculine, so we use ningún instead of ninguno.

Higher Tier: More Complex Usage of Indefinite Adjectives

For higher-tier students, you may be required to use indefinite adjectives in more complex sentences, including combining multiple indefinite adjectives or using them in conjunction with other grammar structures.

Examples:

  • Tengo varios amigos, pero no todos son simpáticos.
    (I have several friends, but not all of them are friendly.)
    Here, varios (several) is used to describe amigos (friends), and todos (all) is used with the plural noun amigos.
  • Cada día, hay más gente en el parque.
    (Every day, there are more people in the park.)
    Cada (each) is used with día (day), and más (more) is used to describe the increasing quantity of gente (people).
  • No tengo ningún dinero para comprarlo.
    (I don't have any money to buy it.)
    Here, ningún is used to express the absence of dinero (money), which is masculine and singular.

Negative Forms with Indefinite Adjectives

When you want to say something like "none" or "not any", you can combine the negative word "no" with the indefinite adjectives.

  • No tengo ningún dinero. (I don’t have any money.)
    Ningún is used to mean "none" or "not any", and it agrees with the masculine noun dinero (money).
  • No hay ninguna respuesta. (There is no answer.)
    Ninguna is used to mean "none", and it agrees with the feminine noun respuesta (answer).

Summary of Key Points

Indefinite adjectives describe unknown or unspecific quantities: mucho (a lot), poco (little), cada (each), algunos (some), ningún (none).

Agreement in gender and number: Indefinite adjectives must agree with the gender and number of the noun they modify.

Shortened forms of alguno and ninguno: Algún and ningún are used before singular masculine nouns.

Negative forms: To say "none" or "not any", use ningún (masculine) and ninguna (feminine) before the noun.
