Spanish has two verbs that mean "to be": ser and estar.
Although both translate as to be in English, they are not interchangeable. Choosing the wrong one can completely change the meaning of a sentence.

When deciding between ser and estar, ask yourself these 5 questions:
1. Am I describing what something or someone is?
Use SER.
2. Am I describing how something or someone is right now?
Use ESTAR.
3. Am I talking about location?
Use ESTAR (except for events).
4. Am I describing the result of an action?
Use ESTAR.
5. Am I talking about identity, profession, origin, time, relationships, or defining characteristics?
Use SER.
Instead of memorizing long lists of rules, learn ser and estar through meaningful examples and common expressions. Many combinations become natural with repeated exposure:
✓ Soy de México.
✓ Es profesora.
✓ La reunión es en la oficina.
✓ Estoy cansado.
✓ Estamos de vacaciones.
✓ La puerta está abierta.
The more complete phrases you learn, the easier it becomes to choose the correct verb naturally in conversation.
