Using 'Estar'

---

Although it is an extremely common verb, estar can be confusing for many Spanish students because it is usually translated as "to be," same as the verb ser. Although they can often be translated the same way, ser and estar are distinct verbs with distinct meanings and are seldom synonymous.
It is probably most helpful to learn the two verbs separately, seeing how they function. After you've read this lesson, make sure you read the lesson on ser to see how it is used. And if you don't understand any terms on this page, be sure to look them up in the links to other lessons.

Here are the main uses of estar:

To indicate a state or condition, often one resulting from a change:

Examples: Estaba enferma. (She was sick.) Estoy muy triste. (I am very sad.)

To indicate location:

Examples: Las torres gemelas estaban en Nueva York. (The twin towers were in New York.) Estamos en casa. (We are at home.)

Preceding de to form various idioms of condition or state:

Examples: Estamos de viaje.(We are on a trip.) No están de broma. (They aren't kidding around.)

With a present participle to form a progressive tense:

Examples: Está cantando. (He is singing.) Estaba estudiando en la biblioteca. (She was studying in the library.) Estaré trabajando. (I will be working.)

To indicate suitability:

Examples: La camisa te está pequeño. (The shirt is small for you.) Me estaba bien la comida. (The meal tasted good to me.)
