* el (masculine singular)
* la (feminine singular)
* los (masculine plural)
* las (feminine plural)
Here's a breakdown:
* el is used before masculine singular nouns. For example: el libro (the book), el gato (the cat).
* la is used before feminine singular nouns. For example: la mesa (the table), la casa (the house).
* los is used before masculine plural nouns. For example: los libros (the books), los gatos (the cats).
* las is used before feminine plural nouns. For example: las mesas (the tables), las casas (the houses).
Important Note: The definite article is always used before a noun in Spanish, even if it's already clear from context what is being referred to.
For example: "I saw the dog." You would say "Vi el perro," not "Vi perro."
