Español — Ser vs estar with adjectives
Both ser and estar mean "to be", but ser marks an inherent quality and estar marks a state or result. With some adjectives the choice changes the meaning entirely: es aburrido (he is boring) vs está aburrido (he is bored).
How it works
Use ser for what something essentially is (identity, nature, defining trait): Ana es lista (Ana is clever). Use estar for a condition or result at a moment (mood, state, outcome): Ana está lista (Ana is ready). The adjective agrees in gender and number in both cases.
Meaning shifts
| Adjective | With ser | With estar |
|---|---|---|
| aburrido | boring | bored |
| listo | clever, smart | ready |
| rico | rich, wealthy | tasty, delicious |
| verde | green (colour) | unripe |
| malo | bad (evil, poor quality) | ill, sick |
| vivo | lively, sharp | alive |
| bueno | good (kind, quality) | tasty; well (recovered) |
Good to know
The trap is treating estar as "always temporary". With these adjectives estar signals a result, not just a short duration: está muerto (he is dead) is permanent yet uses estar because it is the result of a change. Conversely es rico describes wealth, while está rico praises the food — never confuse the two at the dinner table.
