In Spanish, there are two types of articles: definite and indefinite.

These articles need to agree with the nouns they go with. This means they should match in gender, which is masculine or feminine, and in number, which is singular or plural.

Definite Articles (for specific things)

These articles refer to something very specific:

• el: used for masculine singular (like el libro - the book)

• la: used for feminine singular (like la casa - the house)

• los: used for masculine plural (like los libros - the books)

• las: used for feminine plural (like las casas - the houses)

Indefinite Articles (for non-specific things)

These articles do not point to anything specific:

• un: used for masculine singular (like un libro - a book)

• una: used for feminine singular (like una casa - a house)

• unos: used for masculine plural (like unos libros - some books)

• unas: used for feminine plural (like unas casas - some houses)

Examples:

• Definite: El perro es grande. (The dog is big.)

• Indefinite: Un perro es grande. (A dog is big.)

Important Tip:

Remember to always match the article with the noun in both gender and number!
