There are two different articles in Spanish, the definite article and the indefinite article.
The definite article in English is “The”. It pertains to a specific object. Example: the pencil, the paper
There are two indefinite articles in English “A” and “An”. These articles apply to a non-specific object. Example: A pencil (in a group of pencils), An apple (in a group of apples)
In Spanish, both types of articles must agree in gender and in number. If they do not agree in gender and in number, Mrs. Garza is going to know you don’t know what you are doing.

All nouns in Spanish carry an article with them, either definite or indefinite. On your vocabulary quizzes, you will be required to write either article for credit for the vocabulary quiz question... FYI.
