What Are Indefinite Articles?

Indefinite articles are words used to refer to non-specific nouns. In English, the indefinite articles are "a" and "an." In Spanish, the indefinite articles are "un," "una," "unos," and "unas." These articles help to specify the gender and number of the nouns they modify, which is a key aspect of Spanish grammar.

Gender and Number in Spanish

Before diving into the use of indefinite articles, it's essential to understand the concepts of gender and number in Spanish. Nouns in Spanish are either masculine or feminine, and they can be singular or plural. The indefinite articles must agree with the noun in both gender and number.
