In the previous lesson, we’ve learnt about Spanish definite articles. And while definite articles in Spanish are the English equivalent of "the", indefinite articles in Spanish are the equivalents of "a", "an", "some", or "a few" in English. In this article, we will show you the definition of Spanish indefinite articles and their usage.

Spanish indefinite articles


Spanish indefinite articles are words used to refer to nouns which are non-specific. 


  • Just like definite articles, Spanish indefinite articles must match the number and the gender of the nouns that they modify.

See gender of nouns in Spanish for more information!

¿Hay un elefante en este zoológico? - Is there an elephant in this zoo?

Quiero una galleta - I want a cookie
