Frequently Asked Questions
So 'estar + past participle' is just like a normal adjective?
Exactly! You can think of it that way. In 'la puerta está cerrada' (the door is closed), the word 'cerrada' works just like an adjective describing the door. It even has to agree in gender and number (las puertas están cerradas).
Why does 'ser + past participle' sound so formal?
It's the true 'passive voice', which is more common in formal writing like news articles, historical texts, and legal documents. In everyday conversation, Spanish speakers often prefer other constructions, like using 'se' (e.g., 'Se venden casas' instead of 'Casas son vendidas').
