Passive participles — past and present
Passive participles describe what's been done TO something. The past passive (the most common) is used both as a long-form adjective and a short-form predicate — that's how Russian builds passive sentences.
Past passive: -нный / -тый
Built from PERFECTIVE transitive verbs. The most common ending is -нный: - прочитать → прочитанный = (the one) read [through] - написать → написанный = written - сделать → сделанный = done / made - открыть → открытый = opened (uses -тый) The long form declines like an adjective: прочитанная книга = a book that has been read.
Short form = passive sentence
The short form (-н, -на, -но, -ны / -т, -та, -то, -ты) acts as a predicate: - Книга прочитана. = The book has been read. - Дверь открыта. = The door is open / has been opened. - Письмо написано Анной. = The letter was written by Anna. The agent (who did it) appears in the instrumental (Анной).
Present passive — rare in speech
Formed from imperfective verbs with -мый: уважаемый (respected), любимый (beloved). These mostly survive as adjectives in their own right rather than productive participles.
Why it matters
Russian uses these short-form passives in headlines, news, and any time the doer doesn't matter: - Магазин закрыт. = The store is closed. - Концерт отменён. = The concert is cancelled. - Билеты проданы. = Tickets are sold (sold out). This is everyday Russian — even though the long-form participles are more 'literary'.
