Impersonal Reflexive Construction with Se

Level 4

The impersonal se construction (neosobní reflexivum) is used to make generic statements, express rules, or describe customs without specifying who is doing the action. It translates to English phrases using 'one does', 'people do', or 'it is done'.

How It Works

This pattern is extremely frequent in everyday Czech, used for everything from casual speech to formal public signs.

General Human Agent:
The most common use of the impersonal se is to express a general, unspecified human agent, equivalent to 'one', 'people', or 'they' in English. It is widely used for general rules, public signs, and general statements: Tady se nekouří (No smoking here / One doesn't smoke here).

The Evaluative Construction:
When combined with an evaluative adverb (like dobře or špatně) and a dative experiencer, the focus shifts away from the agent's effort. It implies the environment or object naturally facilitates the action. Note that this construction can be impersonal and subjectless (Dobře se mi tu pracuje) or personal with a nominative subject if a transitive verb is used (Ta kniha se čte dobře).

Crucial Distinctions:

  • No Subject: Unlike English, which requires dummy subjects like 'it' or 'there', the Czech subject slot must remain completely empty.
  • Past and Conditional Tenses: Because there is no subject, the verb must take the default neuter singular ending -lo in the past tense and conditional (e.g., pracovalo se).
  • Vs. Reflexive Passive: The impersonal se results in a completely subjectless sentence (Tady se pracuje = Working happens here). It is typically formed with intransitive verbs, or with transitive verbs when their direct object is omitted or generalized (Tady se vaří = Cooking happens here). In contrast, when a transitive verb's direct object is expressed and promoted to the nominative case, it forms the reflexive passive (Knihy se prodávají = Books are sold). Note that the reflexive passive is generally restricted to the 3rd person; using it in the 1st or 2nd person usually defaults to a literal reflexive meaning.
  • Not a Verb Form: Modern linguistics clarifies that se here is an autonomous syntactic clitic that deletes the subject, not a morphological verb affix.
  • Incompatible with Reflexive Verbs: This construction cannot be used with inherently reflexive verbs (inherent reflexive verbs with se) such as smát se (to laugh) or dívat se (to look). The clitic se cannot be doubled, and dropping one se reverts the sentence to a specific 3rd person subject (směje se means 'he/she/it laughs', not 'one laughs'). It is also generally incompatible with verbs that take the reflexive clitic si (e.g., stěžovat si).

Examples (5)

  1. Tady se nekouří.

    No smoking here.

    Word by Word: Here one does not smoke.

    A classic example of a general prohibition. The verb is in the 3rd person singular, and there is no subject.

  2. Jak se tam jde?

    How does one get there?

    Word by Word: How does one go there?

    A highly common generic statement asking about a general route or custom, completely lacking a subject.

  3. Tady se pracovalo.

    People worked here. / Work was done here.

    Word by Word: Here it worked itself.

    An impersonal statement in the past tense. Because there is no subject, the verb must take the neuter singular '-lo' ending.

  4. Dobře se mi tu spalo.

    I slept well here.

    Word by Word: Well it slept itself to me here.

    The evaluative construction in the past tense. The dative 'mi' shows the experiencer, and the verb takes the neuter '-lo' ending.

  5. O tom se nemluví.

    One doesn't talk about that. / People don't talk about that.

    Word by Word: About that one does not talk.

    Used to express a general social rule or taboo.

Common Mistakes

  • Adding a dummy subject like 'to' or 'ono'.

    Tady to se nekouří.
    Tady se nekouří.

    Because English grammar demands a subject ('it' or 'there'), learners often try to force a pronoun into the empty subject slot. Czech requires the subject slot to remain completely empty.

  • Using a nominative pronoun instead of a dative experiencer in evaluative constructions.

    Já se dobře spím.
    Dobře se mi spí.

    When describing how an environment facilitates an action for someone, the person experiencing it must be in the dative case (e.g., 'mi'), not the nominative ('já').

  • Violating the second-position rule for clitics.

    Tady nekouří se.
    Tady se nekouří.

    The particle 'se' is a Wackernagel clitic. It must attach phonologically to the first stressed constituent of the clause, occupying the strict second position.

Learn This First

To learn the impersonal reflexive construction, you first need to understand how reflexive verbs work in Czech and how the particle 'se' is placed in a sentence. Additionally, since these constructions always use the third-person singular form of the verb, you should be familiar with standard present tense conjugations.
