Spanish nouns are masculine or feminine, and their articles must match both gender and number. This cheat sheet helps students choose the correct form of the, a, an, some, and the noun endings that often signal gender. It is useful because article mistakes can change the grammar of an entire sentence.
Students in grades 6-8 can use it as a quick reference while reading, writing, or speaking Spanish.
The main definite articles are el, la, los, and las, which all mean the. The main indefinite articles are un, una, unos, and unas, which mean a, an, or some. Many masculine nouns end in -o, and many feminine nouns end in -a, but there are important exceptions.
Articles, nouns, and adjectives should agree in gender and number, such as el libro rojo or las casas grandes.

Common Mistakes to Avoid
- Using el with every Spanish noun is wrong because nouns have gender, so feminine singular nouns need la, such as la escuela.
- Forgetting to change the article in the plural is wrong because articles must match number, so el libro becomes los libros, not el libros.
- Assuming every noun ending in -a is feminine is wrong because some common nouns are exceptions, such as el día.
- Using una before a masculine noun is wrong because the indefinite article must match gender, so it is un cuaderno, not una cuaderno.
- Making only the noun plural and not the article is wrong because Spanish requires agreement, so the correct form is las amigas, not la amigas.
