Here's how it breaks down:
* Es: This is the third-person singular form of the verb "ser" (to be).
* La: This is the feminine singular definite article, meaning "the".
Examples:
* Es la casa de mis padres. (It is the house of my parents.)
* Es la mujer que me gusta. (She is the woman I like.)
It's important to remember that the gender of the noun following "es la" will determine whether you are talking about a male or female.
