Articles are the short words that come before the nouns. For example, “the pen,” “a telephone,” and so on. We have two kinds of articles in English: definite articles (the) and indefinite articles (a/some).
Spanish also has two kinds of articles, but since Spanish nouns have gender, Spanish articles do, also. Like with nouns, the presence of the letter a in the article means it’s feminine, and when it ends in s, that means it’s plural.
Definite Article: the
The article the can be singular or plural, and feminine or masculine, depending on the noun it refers to.
|Masculine||el (libro)||los (libros)|
|Feminine||la (silla)||las (sillas)|
*Note that the singular masculine definite article is el, not lo.
Indefinite Articles: a/some
The singular of the indefinite article is a, as in “a book.” The plural of the indefinite article is some, as in “some books.”
|Masculine||un (libro)||unos (libros)|
|Feminine||una (silla)||unas (sillas)|
*Note that the singular masculine indefinite article is un, not uno.
