This is the 3029th most frequent Russian word.
закрыта
"Закрыта" means "closed" in English.
The word 'закрыта' is used as a predicate adjective in the feminine singular form to describe the state of 'дверь' (door).
Дверь закрыта.
The door is closed.
Here, 'закрыта' is incorrectly used and should be changed to 'закрыт' to match the gender of 'магазин' (shop), which is masculine; however, the context aims to describe the shop's status.
Магазин закрыта сегодня.
The shop is closed today.
In this sentence, grammatical gender agreement is incorrect once again. 'Гараж' is masculine, so 'закрыт' should be used instead of 'закрыта'. The word usage intends to indicate the state of the garage being closed.
