When do I use ser and when do I use estar in Spanish?
Short answer
Both mean “to be”, but they answer different questions. Use ser for what something is: identity, profession, origin, characteristics, what it is made of, time and dates, and where an event takes place. Use estar for how or where something is: the location of people and things, states and conditions, the result of a change, and ongoing actions (estoy comiendo).
The common shortcut “ser is permanent, estar is temporary” works surprisingly often — and fails in some very common sentences: está muerto (he is dead) uses estar, and es joven (she is young) uses ser. Thinking “essence vs state” is more reliable.

Why “permanent vs temporary” misleads
| Sentence | Verb | Why |
|---|---|---|
| Está muerto. | estar | death is the result of a change — a state |
| Es joven. | ser | youth is treated as a characteristic, even though it changes |
| La boda es en Sevilla. | ser | an event’s location takes ser |
| El hotel está en Sevilla. | estar | a thing’s location takes estar |
| Es soltero. | ser | marital status is treated as a classification |
| Está casado. | estar | (usually) the result of getting married |
So ask: Am I saying what it is — or how/where it is right now?
