Spanish has two verbs for “to be”: ser and estar. English uses one, so the choice feels strange at first. The good news: one question settles most cases.
What is it, or how is it?
Use ser for what something is: identity, origin, profession, character, time.
- Soy Ana. Soy de Valencia. — I’m Ana. I’m from Valencia.
- Mi hermano es médico. — My brother is a doctor.
- Son las tres. — It’s three o’clock.
Use estar for where something is and how it is right now: location, mood, a state that can change.
- Estoy en casa. — I’m at home.
- María está cansada hoy. — María is tired today.
The same adjective, two meanings
Some adjectives change their meaning with the verb:
| ser | estar | |
|---|---|---|
| aburrido | boring | bored |
| listo | clever | ready |
| rico | rich | tasty |
La película es aburrida — the film is boring. Estoy aburrido — I’m bored.
Common mistakes
- Soy cansado → Estoy cansado: tiredness is a state.
- La fiesta está en mi casa → La fiesta es en mi casa: an event “takes place”, so it takes ser, even with a place.
