These indefinite articles are: UN, UNA, UNOS, UNAS.

The same way Spanish Definite Articles are the equivalent for the English definite article (THE), Spanish indefinite articles correspond to the Engilsh forms A and SOME. Let’s see how it works:

UN, UNA = ONE, A, AN

UNOS, UNAS = SOME

And here we have they classifcation according to genre and number:

MASCULINE / SINGULAR: UN

MASCULINE / PLURAL: UNOS

FEMININE / SINGULAR: UNA

FEMININE / PLURAL: UNAS

Of course, you’d like to read some examples:

Masculine, singular indefinite article UN

Un árbol grande.
( A big tree OR One big tree.)

Un niño alto.
( A tall boy OR One tall boy)


Feminine, singular indefinite article UNA

Una flor amarilla.
( A yellow flower OR One yellow flower.)

Una niña alta.
( A tall girl OR One tall girl)


Masculine, plural indefinite article UNOS

Unos árboles grandes.
( Some big trees.)

Unos niños altos.
( Some tall boys)


Feminine, plural indefinite article UNAS

Unas flores amarillas.
( Some yellow flowers.)

Unas niñas altas.
( Some tall girls)

Now that we know how to identify these Spanish indefinite articles, let ‘s review some interesting points about their use.

• We’ll use the masculine plural article (UNOS) as long as , at least, one of the creatures of the group is masculine. For example, if we are talking about a group of seven (6 female dogs and 1 male dog) we’ll say unos perros.
  
  
• Spanish language omits, in certain cases, the use of the indefinite articles:




• When we refer to a person’s profession or job: El es profesor (He is a teacher)


• When we refer to a person’s religion: Ella es budista (She is a Buddhist)


• Before “thousand” (mil) and “hundred” (cien): Tengo cien dólares ( I have a hundred dollars)
  
• Whe we use “qué” in a exclamation: ¡Qué gato! (What a cat!)

If you are just a beginner, just remember that you don’t have to learn all these exceptions. In fact, the use of indefinite articles is a question of practice and use, so, the only thing you have to do right now is trying to learn and remember the genre of any new Spanish word you learn. This way, you’ll use the correct indefinite article with it.
