The definite articles in Spanish are: el, la, los and las.
There are 4 different forms because the article must match the gender and number of the noun.
The articles usually precede the nouns. An example of this is la casa.
Spanish is logical in that it is usually easy to find out whether a noun is masculine or feminine.
If it ends with a o, it is male.
If it ends in a a, it is female.
We use the article El for a masculine noun and La for a feminine noun. If a word ends with another letter, for example Mujer or País, it can be both. In addition, of course, there are some irregularities where the noun ends in an o but is feminine, or ends in an a but is masculine. Therefore, in some cases, there is no getting around learning the article.
In the plural, el becomes los and la becomes las. The plural can usually be recognized by the noun ending s as in las casas.
