Ser vs estar: the difference explained
English has one verb for “to be”. Spanish has two: ser and estar. “I am tall” and “I am tired” use different verbs in Spanish, which makes this one of the first big hurdles for English speakers. The good news: there is a clear logic behind the choice.
The rule of thumb: ser describes what someone or something is (identity, characteristics, origin). Estar describes how or where someone or something is (a state or a location).
When to use ser
ser for what someone or something is:
- Identity and profession: Soy profesor. (I'm a teacher.) Spanish leaves out the “a” here.
- Characteristics and personality: Ella es simpática. (She's nice.)
- Origin: Somos de Canadá. (We're from Canada.)
- Time and dates: Son las tres. (It's three o'clock.)
- Material and possession: La mesa es de madera. (The table is made of wood.)
- Where an event takes place: La fiesta es en mi casa. (The party is at my house.)
When to use estar
estar for states and locations:
- Location: El libro está en la mesa. (The book is on the table.)
- Temporary state: Estoy cansado. (I'm tired.)
- Mood and feelings: Está contenta. (She's happy.)
- Action in progress: Estoy aprendiendo español. (I'm learning Spanish.) The English “am/is/are + -ing” for something happening right now becomes estar + gerund.
- Result of a change: La puerta está abierta. (The door is open.) This is also why Spanish says está muerto (he's dead).
A memory aid: DOCTOR and PLACE
Many teachers in English-speaking countries use two acronyms. DOCTOR stands for the uses of ser: Description, Occupation, Characteristic, Time, Origin, Relationship. PLACE stands for the uses of estar: Position, Location, Action, Condition, Emotion.
The acronyms cover most everyday cases. Keep the two exceptions above in mind: events take ser even when you say where they happen, and muerto (dead) takes estar even though death is permanent.

Frequently asked questions

Ser is for what something is: identity, characteristics, origin, time. Estar is for how or where something is right now: states, feelings, location. If the description could change from one day to the next, estar is usually the right choice.

Estoy en Madrid. Use estar for where a person or thing is, even if you live there permanently. The exception is events: La reunión es en Madrid (The meeting is in Madrid) takes ser.

It depends on what you mean. Estoy aburrido means “I'm bored”, which is how you feel right now. Soy aburrido means “I'm boring”, which is a characteristic. Listo works the same way: estar listo is to be ready, ser listo is to be clever.
