The Passive in Serbian: se-Passive vs. the Past Participle
Serbian has two ways to say something is done to a subject, and the difference between them is the whole point of this lesson: one describes an ongoing process, the other a finished result. English blurs this line, so pick the wrong one and a native speaker will hear it immediately. The first is the se-passive (refleksivni pasiv). You take the active verb in the 3rd person (singular or plural to match the subject) and add the little particle se. This describes an action in progress or a general truth, and crucially it names no agent — nobody does the doing. "Knjiga se čita" means "the book is being read," "Kuća se gradi" is "the house is being built" (right now, still going up), and "Ovde se govori srpski" is "Serbian is spoken here." Think of it as the Serbian equivalent of the English "is being read" or the impersonal "is spoken." "Pismo se piše" — "the letter is being written." The second is the participial passive: the verb biti (to be) plus the past passive participle (trpni glagolski pridev), which ends in -n or -t — forms like sagrađen, otvoren, napisan. This describes the result, the finished state. "Most je sagrađen" — "the bridge is built" (it stands there, done). "Pismo je napisano" — "the letter is written / has been written." "Kuća je sagrađena" — "the house is built." The English hook is simple: "is being built" (process) maps onto se, while "is built" or "was built" (result) maps onto biti + participle. Here is the part English does not prepare you for. That participle is really an adjective in disguise, and like any Serbian adjective it agrees with the subject in gender and number. Masculine takes a bare ending (most je sagrađen), feminine adds -a (kuća je sagrađena), neuter adds -o (pismo je napisano), and the plural takes -e (mostovi su sagrađeni → sagrađene for feminine plural). Watch the tricky nouns: vrata ("door") is grammatically neuter plural, so it is "Vrata su otvorena" — not the singular form you might expect. Three mistakes trip up English speakers. First, leaving the participle in its default masculine form because English has no agreement: "Vrata su otvoren" is wrong; it must be "Vrata su otvorena." Always check the gender and number of the subject before you choose the ending. Second, using the participle for something still in progress: "Kuća je sagrađena" claims the house is finished, so if it is still going up you need the process form "Kuća se gradi." Third, getting the form of biti wrong — it has to agree in person and number too (je for singular, su for plural). And a stylistic note: Serbian leans on the active voice far more than English does, so don't reach for the passive out of habit. When you do need it, let the process/result split decide: se for what is happening, biti + participle for what is done.
Examples
- Knjiga se čita. The book is (being) read.
- Most je sagrađen. The bridge was built.
- Vrata su otvorena. The door is open(ed).

-
Serbian has two ways to drop the doer and say a thing was done. Mix them up and the sentence sounds broken.
-
The passive lets you talk about an action without naming who does it. News, signs, and formal writing live on it. Serbian builds it in two ways, and each one is for a different job.
-
Here is the split. The se-passive uses the little word se on an active verb, and it describes a process — something in progress or done in general. The participial passive uses biti, to be, plus a past passive participle, and it describes a finished result.
-
Start with the se-passive. Take an active verb, add se, and the object becomes the subject. The action is simply happening. Knjiga se čita. The book is being read.
-
It is perfect for general truths and ongoing processes, where naming a doer would be pointless. Ovde se govori srpski. Serbian is spoken here.
-
Now the participial passive. You take biti, the verb to be, and add a past passive participle — a special form built from the verb. For most verbs it ends in -n or -t. sagrađen built, otvoren opened, napisan written.
-
This form names the finished result. The bridge is not being built — it stands built. Most je sagrađen. The bridge was built.
-
And here is the catch with the participle. It is an adjective in disguise, so it must agree with the subject in gender and number. Most is masculine, so sagrađen. Make the subject feminine, neuter, or plural, and the ending changes.
-
Watch the agreement live. The subject is feminine singular, so the participle takes an -a. Kuća je sagrađena. The house has been built.
-
And here the subject is neuter plural — vrata, doors — so the participle ends in -a for that pattern. Vrata su otvorena. The door is opened.
-
Compare the two side by side and you feel the difference. The se-passive paints the process; the participle states the result. Pismo se piše. Pismo je napisano. The letter is being written. The letter is written.
-
Now the mistake everyone makes. The participle is not frozen — leave it in the default masculine form and it clashes with the subject. The doors are neuter plural, so the ending must follow.
-
And do not reach for the participle when you mean an ongoing process. To say the house is being built right now, you want the se-passive — the participle would say it already stands finished.
-
So keep three things. Verb plus se is the process passive. Biti plus a participle is the result passive. And that participle always agrees with its subject — sagrađen, sagrađena, sagrađeno, sagrađene.
