The A1 rule gets you a long way, then breaks. Está muerto is permanent. Es joven is temporary. The real distinction is different: ser classifies, estar describes a state.
Ser says what something is — which category it belongs to. Estar says how something is right now, compared to how it usually is, or how it strikes you.
This is the heart of B2 ser/estar. The same adjective means two different things depending on the verb.
| Adjective | with SER | with ESTAR |
|---|---|---|
| listo | clever | ready |
| aburrido | boring | bored |
| rico | rich | tasty |
| verde | green (colour) | unripe |
| malo | bad (person) | ill |
| bueno | good (person) | tasty / attractive |
| vivo | sharp, lively | alive |
| despierto | bright, alert | awake |
| orgulloso | arrogant | proud of |
| atento | considerate | paying attention |
| negro | black | furious |
| abierto | open-minded | open (not shut) |
Even with ordinary adjectives, estar signals that something strikes you as different from usual — including with food, appearance and mood.
| Always SER | Always ESTAR |
|---|---|
| time, dates: Son las tres. | location: Está en Madrid. |
| origin: Soy de México. | progressive: Estoy comiendo. |
| material: Es de madera. | de acuerdo: Estoy de acuerdo. |
| possession: Es mío. | de vacaciones: Están de vacaciones. |
| events: La fiesta es en mi casa. | bien / mal: Está bien. |
| impersonal: Es importante. | a punto de: Está a punto de salir. |
The classic trap: location of a thing takes estar — El museo está en el centro. But location of an event takes ser — La reunión es en el museo. If it happens rather than sits there, use ser.
Why estar with food is a compliment. La sopa es buena classifies soup as a good kind of food in general. La sopa está buena says this soup, right now, tastes great. Use ser at the dinner table and you'll sound like you're reviewing a category rather than praising the cook.
