Important Points

  • Indefinite articles are used when mentioning something for the first time or when it is not important to specify exactly which one.
  • They can also be used to express approximate quantities (e.g., unos diez minutos = about ten minutes).
  • In Spanish, unlike English, indefinite articles are usually kept even when talking about professions, religions, or nationalities (e.g., Es un doctor = He is a doctor).

Summary

Indefinite articles in Spanish are un, una, unos, and unas. They mean "a," "an," or "some" and are used to introduce non-specific nouns. Always match the article to the nounโ€™s gender and number.
