zabránit + Dative

Dative After Zabránit

Level 5

In Czech, the verb zabránit (to prevent) does not take a direct object and always requires the dative case, unlike the English transitive verb 'prevent'.

How It Works

The perfective verb zabránit (to prevent, avert) is highly frequent in standard Czech, especially in journalistic, legal, and official contexts. Unlike the English verb 'prevent', it does not take a direct object and strictly governs the dative case. The core rule is simple: zabránit takes the dative for whatever is being stopped, whether it is an inanimate event or an animate person.

1. Preventing an event (zabránit čemu)
When preventing an event, the noun must be in the dative. Many prevented events are feminine nouns ending in -a (e.g., nehoda, srážka, katastrofa). In the dative singular, the ending -ě/-e triggers important consonant changes: d/t/n palatalize to ď/ť/ň (nehoda → nehodě), labials p/b/f/v are pronounced with an inserted [j] sound (katastrofa → katastrofě, do not write 'katastrofje'), while m followed by ě is pronounced as [mňe]. Velars undergo mutation (k → c, h → z, ch → š, e.g., srážka → srážce). Additionally, the consonant r changes to ř. A very useful shortcut in formal contexts is using verbal nouns ending in -ní (e.g., zabránit šíření viru), as they do not change their ending in the dative singular.

2. Preventing someone from an action
To express preventing a person from doing something, use the dative for the person and either v + locative for the action (zabránit mu v útěku), a subordinate clause (zabránit (tomu), aby..., where the pronoun tomu is optional), or an infinitive (zabránit mu utéct). The infinitive is a standard, fully grammatical alternative to v + locative or a subordinate clause. A notable feature of Czech verbs of preventing is pleonastic (redundant) negation in the subordinate clause. Traditional grammars treat Zabránil mu, aby odešel and Zabránil mu, aby neodešel as meaning the same thing (prevented him from leaving), but be aware that modern usage sometimes employs true negation to mean the opposite, so context is key.

3. Impersonal Passive
A very common phrase is the impersonal reflexive passive expressing inevitability: tomu se nedá/nedalo zabránit (it cannot/could not be prevented). In official contexts, the periphrastic passive is also highly frequent: tomu bylo zabráněno. It is crucial to note that the pronoun must remain in the dative case (tomu, not to) even in the passive voice, a common pitfall for English speakers.

4. Aspect and False Friends
Learners often confuse zabránit with the base verb bránit. While bránit + dative means 'to hinder', bránit + accusative means 'to defend'. Zabránit never means 'to defend' and never takes the accusative. While bránit is technically the imperfective counterpart for the 'hinder' meaning, its ambiguity with 'to defend' makes zabraňovat the preferred, unambiguous secondary imperfective for learners. Because zabránit is perfective, its present-tense forms (zabráním, zabráníš) express the future tense ('I will prevent') as a perfective present. To say 'I am preventing' right now, you must use the imperfective zabraňuji/zabraňuju.

  1. Řidič už nedokázal nehodě zabránit.

    The driver was no longer able to prevent the accident.

    Word by Word: Driver already not-managed accident to-prevent.

    The feminine noun 'nehoda' changes to the dative 'nehodě', triggering the d → ď palatalization.

  2. Včasný zásah hasičů zabránil katastrofě.

    The timely intervention of the firefighters prevented a disaster.

    Word by Word: Timely intervention of-firefighters prevented disaster.

    The ending -ě after the labial consonant 'f' is pronounced with an inserted [j] sound (katastrofě).

  3. Strojvedoucí naštěstí zabránil srážce vlaků.

    The train driver fortunately prevented the collision of the trains.

    Word by Word: Train-driver fortunately prevented collision of-trains.

    The feminine noun 'srážka' changes to 'srážce' in the dative, demonstrating the k → c consonant mutation.

  4. Policista jim zabránil v útěku.

    The police officer prevented them from escaping.

    Word by Word: Police-officer them prevented in escape.

    To prevent someone from an action uses the dative pronoun ('jim') and v + locative ('v útěku').

  5. Musíme jim zabránit odejít.

    We must prevent them from leaving.

    Word by Word: We-must them to-prevent to-leave.

    Using the dative ('jim') followed directly by an infinitive ('odejít') is a standard, fully grammatical alternative to 'v + locative' or a subordinate clause to express preventing someone from an action.

  6. Byla to nehoda, nedalo se tomu zabránit.

    It was an accident, it couldn't be prevented.

    Word by Word: Was it accident, not-gave itself to-that to-prevent.

    The impersonal reflexive passive 'nedalo se tomu zabránit' is a very common phrase expressing inevitability.

Common Mistakes

  • Using the accusative case instead of the dative for the prevented event.

    Řidič nedokázal zabránit nehodu.
    Řidič nedokázal zabránit nehodě.

    Due to negative transfer from English, learners often treat 'zabránit' as taking a direct object. In Czech, it strictly requires the dative case (čemu) instead of the accusative.

  • Translating 'prevent from' literally using the preposition 'od'.

    Policie mu zabránila od odchodu.
    Policie mu zabránila v odchodu.

    To express preventing someone from doing something, Czech uses 'v + locative' (v čem) or an infinitive, never 'od + genitive'.
