The useful distinction
Ser classifies or identifies; estar locates or presents a state. The distinction is semantic, so either verb can describe something long-lasting or brief.
- Ana es lista.Ana is clever.
- Ana está lista.Ana is ready.
Location has one important exception
Use estar for the location of people and things. Use ser to state where an event takes place: El concierto es en el parque.
A better study method
Learn contrasts in complete sentences. Adjectives such as aburrido, seguro, rico, and verde can change meaning depending on the verb.
