Estar is the second verb that translates as "to be" in English. Where ser points at who or what something is, estar points at how, where, and how it's going right now. If ser is the identity card, estar is the snapshot — an instant photograph of a location, a state, a mood, or an action in progress.
For English speakers, the challenge is not memorizing the forms — those are quick — but learning to split "to be" into two different verbs that overlap in English but feel completely distinct in Spanish. By the time you finish this page, you should know exactly when to reach for estar instead of ser, and why the two are not interchangeable.
Conjugation
| Subject | Conjugation | Pronunciation hint |
|---|---|---|
| yo | estoy | es-TOY |
| tú | estás | es-TAS |
| él / ella / usted | está | es-TA |
| nosotros / nosotras | estamos | es-TA-mos |
| ellos / ellas / ustedes | están | es-TAN |
Notice the written accents on every form except yo and nosotros. These accents are not optional — they are part of the correct spelling and they show where the stress falls. Forget them, and the word is technically misspelled, and in one case (está vs esta) you change the meaning entirely.
The yo form estoy is the one irregular-looking member of the set. It ends in -oy, the same ending you see in soy (ser), doy (dar), and voy (ir). Think of them as a little family of four: soy, doy, voy, estoy.
The Six Main Uses of Estar
English uses one verb ("to be") where Spanish uses two, so it helps to have an explicit list of situations that demand estar. There are six big ones.
1. Location of things and people
Use estar whenever you're talking about where something or someone is, regardless of whether the location is permanent or temporary. Even a mountain range, which never moves, still takes estar for its location.
Estoy en la biblioteca.
I am in the library.
¿Dónde estás ahora?
Where are you now?
Los Andes están en Sudamérica.
The Andes are in South America.
2. Temporary states and emotions
Use estar for moods, emotions, and anything that could change from one moment to the next. If the question "how do you feel right now?" applies, estar is the answer.
Estoy cansado hoy.
I am tired today.
Mi madre está enferma.
My mother is sick.
Estamos muy contentos con la noticia.
We are very happy with the news.
¿Estás enojado conmigo?
Are you mad at me?
Los estudiantes están nerviosos antes del examen.
The students are nervous before the exam.
3. Physical condition
Closely related to feelings: physical conditions that could change. Being sick, injured, clean, dirty, hot, cold — all of these are estar.
El perro está sucio después de jugar en el barro.
The dog is dirty after playing in the mud.
La sopa está caliente, ten cuidado.
The soup is hot, be careful.
Estoy herido en la rodilla.
I'm injured in the knee.
4. Weather (some expressions)
Some weather expressions take estar, especially when describing the sky or the current condition of the day: está nublado ("it's cloudy"), está soleado ("it's sunny"), está lloviendo ("it's raining"). Others use the verb hacer (hace frío, hace calor) — that's a different pattern covered on Weather Expressions.
El cielo está despejado esta mañana.
The sky is clear this morning.
5. Result of a change (past participle + estar)
When something has been acted upon and is now in a resulting state, Spanish uses estar + past participle. The participle works like an adjective and agrees in gender and number with the subject.
La puerta está abierta.
The door is open.
El café ya está frío.
The coffee is already cold.
Las ventanas están cerradas.
The windows are closed.
La tarea está hecha.
The homework is done.
Los platos ya están lavados.
The dishes are already washed.
Notice the difference between ser + participle (the passive voice, describing the action) and estar + participle (the resulting state). La puerta fue abierta por Juan means "the door was opened by Juan" — it describes the event. La puerta está abierta means "the door is open" — it describes the state the door is in now.
6. Progressive tenses
Estar is the auxiliary verb for forming the progressive. It combines with a gerund (-ando / -iendo) to talk about actions in progress right at the moment of speaking.
Estoy estudiando para el examen.
I am studying for the exam.
Ellos están comiendo ahora mismo.
They are eating right now.
¿Qué estás haciendo?
What are you doing?
Mi hermana está durmiendo.
My sister is sleeping.
Ser vs estar: the decision table
When you see an adjective and wonder which verb to pair it with, ask yourself: Am I identifying what this is, or describing how it is right now? The table below summarizes the split.
| Use | Ser or Estar? | Example |
|---|---|---|
| Identity, definition | ser | Ella es doctora. |
| Origin, nationality | ser | Soy de México. |
| Permanent characteristics | ser | El hielo es frío. |
| Time, date | ser | Son las tres. |
| Events: "takes place at" | ser | La fiesta es en mi casa. |
| Location of things/people | estar | Mi casa está aquí. |
| Temporary mood, emotion | estar | Estoy feliz hoy. |
| Physical condition | estar | Estoy cansado. |
| Result of a change | estar | La puerta está abierta. |
| Progressive (-ando / -iendo) | estar | Estoy trabajando. |
Adjectives that switch meaning
Some adjectives change meaning depending on which verb you use. These are worth memorizing as a set.
| Adjective | With ser | With estar |
|---|---|---|
| aburrido | boring | bored |
| listo | clever, smart | ready |
| rico | rich, wealthy | tasty, delicious |
| malo | bad (by nature) | sick, in a bad state |
| verde | green (color) | unripe |
| vivo | lively, sharp | alive |
| seguro | safe (reliable) | sure (certain) |
| atento | considerate | paying attention |
Juan es aburrido.
Juan is a boring person.
Juan está aburrido.
Juan is bored (right now).
La comida es rica.
Food is tasty (in general).
La comida está rica.
The food tastes great (this dish).
English-speaker pitfalls
English "to be" is a trap because it covers both verbs without distinction. The common mistakes fall into a few predictable patterns.
Pitfall 1: Using ser for location of things.
- Incorrect: Mi carro es en el garaje.
- Correct: Mi carro está en el garaje.
Pitfall 2: Using estar for origin.
- Incorrect: Estoy de Colombia.
- Correct: Soy de Colombia.
Pitfall 3: Using ser for emotions.
- Incorrect: Soy feliz hoy. (technically grammatical but suggests you're a perpetually happy person)
- Correct: Estoy feliz hoy. ("I'm happy today.")
Pitfall 4: Dropping the accent on está / están.
- Incorrect: Esta cansado.
- Correct: Está cansado.
Pitfall 5: Using estar for a wedding or concert.
- Incorrect: La boda está en la iglesia.
- Correct: La boda es en la iglesia.
Pitfall 6: Overusing the progressive.
- Incorrect: Estoy trabajando aquí desde 2020. (awkward)
- Correct: Trabajo aquí desde 2020.
Extended dialogue
The exchange below uses estar in almost every sentence so you can see the verb in action across several of its uses at once.
Ana: ¡Hola, Luis! ¿Cómo estás? Luis: Estoy un poco cansado. Estuve trabajando toda la mañana. Ana: ¿Dónde estás ahora? Luis: Estoy en el café de la esquina. ¿Y tú? Ana: Estoy en casa. La puerta está abierta, si quieres pasar. Luis: ¿Están los niños contigo? Ana: Sí, están viendo una película. Están muy contentos porque es su favorita. Luis: Perfecto. El día está lindo, voy caminando. Ana: Ten cuidado, las calles están mojadas por la lluvia. Luis: Gracias. Oye, ¿la cena ya está lista? Ana: Todavía no. La sopa está caliente, pero el pan todavía está en el horno.
Notice how many different uses appear: location (¿dónde estás?, estoy en el café), mood (estoy cansado, están contentos), result of a change (la puerta está abierta, las calles están mojadas, la cena está lista), and the progressive (estuve trabajando, están viendo).

- Ser in the Present — the partner verb
- Haber in the Present — "there is / there are"
- Ir in the Present — another core irregular verb
Once ser and estar feel distinct rather than interchangeable, you've crossed one of the biggest thresholds in Spanish. From there, most grammar questions about "to be" answer themselves.
