The Many Faces of se

The little word se is the busiest morpheme in Croatian. A single clitic does the work that English splits among -self, each other, the passive be, the generic one/you/they, and a whole class of verbs that just happen to come with it. Worse — for the learner — one and the same string can carry several of these readings at once, and only the context, the verb, and the animacy of the subject tell them apart. This page lays out the six functions of se side by side, shows how a sentence can be genuinely ambiguous among them, and gives you the cues that resolve it. The mechanics of two of these readings — the passive and the impersonal — are detailed on the se-passive and impersonal, and se as one of three passive strategies on passive strategies compared.

The six readings

These are not six different words — they are six jobs one word does. The skill is reading the cues. The single biggest cue is the animacy and number of the subject: an animate singular subject pulls toward reflexive (1); an animate plural toward reciprocal (2); an inanimate subject toward passive (3) or middle (6); no subject at all signals impersonal (4); and the verb itself tells you when se is inherent (5).

1. True reflexive — the subject acts on itself

The original sense: se is the unstressed object clitic standing for sebe ("oneself"). The subject and the object are the same person, and the action is one you can literally do to yourself.

The diagnostic for a genuine reflexive: you can replace se with the full stressed sebe and add an emphatic sam(a) ("oneself"), and it still makes sense — Pere sebe, pere se sam. If that paraphrase is impossible, you are not dealing with a true reflexive but with one of the other readings.

2. Reciprocal — they act on each other

With a plural (or coordinated) animate subject, se often means "each other" rather than "themselves." Gledaju se normally means "they look at each other," not "they look at themselves." Reciprocity is the natural reading whenever the action is one people typically do to one another.

To force the reflexive reading on a plural ("they look at themselves") you would add sami sebe (Gledaju sami sebe u ogledalu). Left bare, the plural defaults to reciprocal.

3. Passive — the subject undergoes the action

With an inanimate subject and a transitive verb, se typically builds the passive: the grammatical subject is what the action is done to, and the agent is unexpressed. This is Croatian's everyday agentless passive, strongly preferred for processes and general statements.

The subject still agrees with the verb in number and gender — knjige se prodaju (plural). For the full paradigm and its limits (no expressed agent), see the se-passive and impersonal.

4. Impersonal — generic one / people

When there is no grammatical subject at all and the verb sits in the third person singular, se delivers the impersonal — the generic "one / you / people / they" of English. This works even with intransitive verbs, which is exactly where it differs from the passive: a passive needs a patient to promote, but the impersonal has none.

The impersonal is the form behind notices and norms: Ovdje se ne puši ("No smoking here," lit. "one does not smoke here").

5. Inherent — se is part of the verb

A large class of Croatian verbs are reflexiva tantum — they simply come with se lexically, and there is no version of them without it. The se carries no separate "self / each other / passive" meaning; it is part of the dictionary entry. You must memorise these as verb + se units: bojati se (be afraid), smijati se (laugh), nadati se (hope), sjećati se (remember), dogoditi se (happen), šaliti se (joke).

There is no shortcut here — you cannot predict which verbs are inherently reflexive from their meaning. Treat the se as glued on and learn the verb whole.

6. Middle / anticausative — it happens by itself

The middle (or anticausative) se turns a transitive verb into an intransitive "happens by itself" event, with no agent implied at all. Otvoriti means "to open (something)"; otvoriti se means "(for something) to open" — the door opens, nobody opens it. This is the crucial difference from the passive: a passive implies a hidden agent ("the door was opened by someone"); the middle implies none ("the door opened, on its own").

The cue that separates middle from passive is whether an agent is conceivable. Knjiga se prodaje invites "by a seller" (passive); Led se otopio does not invite "by someone" — it is the sun and physics, an event, not a hidden action.

When one sentence is genuinely ambiguous

The readings really can collide. Djeca se peru could be reflexive ("the children wash themselves"), reciprocal ("the children wash each other"), or even passive in a stretched context ("children are being washed"). Croatian resolves this exactly as English does — with disambiguating words:

So when a se-sentence is ambiguous, add a clarifier: sam(a/i) ("by oneself") for reflexive, međusobno / jedan drugoga ("each other") for reciprocal, and let an inanimate subject or an od strane-free context signal passive vs middle. Most of the time the verb's meaning and the subject's animacy settle it without any help.

Common Mistakes

Key Takeaways

• One clitic se, six jobs: reflexive (acts on self), reciprocal (on each other), passive (subject undergoes), impersonal (generic doer), inherent (lexically fixed), middle/anticausative (happens by itself).
• The biggest disambiguator is the subject's animacy and number: animate sg → reflexive, animate pl → reciprocal, inanimate → passive or middle, no subject → impersonal.
• Passive vs middle turns on whether an agent is conceivable: Knjiga se prodaje (someone sells it) vs Led se otopio (no one melts it).
• Inherent verbs (bojati se, nadati se, smijati se, dogoditi se) must be learned whole — the se carries no separate meaning and cannot be dropped.
• Force a reading with a clarifier: sam(a) for reflexive, međusobno / jedan drugoga for reciprocal.
