Verb Negation with Ne-

Level 1

In Czech, you don't use extra words like 'do not' or 'does not'. Instead, you simply attach the prefix ne- directly to the front of the verb.

How It Works

1. Basic Verbs
Attach ne- to the conjugated verb as a single word: vím (I know) → nevím (I don't know).

2. The Verb 'To Be'
For the present tense of být, the negative forms are regular (nejsem, nejsi, etc.) except for 'he/she/it is': je becomes není.

3. Past and Future Tenses
In the past tense, attach ne- to the main verb ending in -l, not the short 'jsem' word: nedělal jsem (I didn't do). In the future tense, attach it to the 'budu' word for imperfective verbs: nebudu dělat (I won't do). For perfective verbs and verbs of motion, attach it directly to the main verb: neudělám (I won't do), nepůjdu (I won't go).

4. Conditional Mood
In the conditional mood ('would'), attach ne- to the main verb (the l-participle), not the auxiliary 'bych/bys': nedělal bych (I wouldn't do).

5. Double Negation
Unlike English, Czech requires negative concord. If you use a negative word like nikdo (nobody) or nic (nothing), the verb must also be negative: Nikdo to neví. (Nobody knows it.)

6. Contrastive Negation
When contrasting two things ('not X, but Y'), ne is written as a separate word: Přijdu, ale ne v pondělí. (I will come, but not on Monday.)

7. Negative Commands
When telling someone not to do something, attach ne- to the imperative form. Negative commands usually require a shift to the imperfective aspect, even if the positive command was perfective: Udělej to! (Do it!) → Nedělej to! (Don't do it!).

8. The "Must Not" Trap
Negating the verb muset (must) creates a false friend for English speakers. Nemuset means 'don't have to' or 'needn't' (lack of obligation). To express 'must not' (prohibition), you must use an entirely different verb: nesmět. For example: Nemusíš tam jít. (You don't have to go there.) vs. Nesmíš tam jít. (You must not go there.)

9. Negative Questions
Starting a question with a negative verb is a common way to be polite in Czech: Nevíte, kde je nádraží? (Do you happen to know where the station is?). When answering a negative question, be careful! To contradict the negative question and say 'yes', use Ale ano (Oh yes) or echo the positive verb. If you just say Ano, it can be confusing.

  1. Zítra nejdu do školy.

    I am not going to school tomorrow.

    Word by Word: Tomorrow not-I-go to school.

    The prefix ne- attaches directly to the present tense verb jdu.

  2. Nerozumím, co říkáš.

    I do not understand what you are saying.

    Word by Word: Not-I-understand, what you-say.

    A standard example of negating a present tense verb.

  3. Petr tady není.

    Petr is not here.

    Word by Word: Petr here isn't.

    The 3rd person singular of 'být' (je) has the irregular negative form 'není'.

  4. Včera jsem nepracoval.

    I didn't work yesterday.

    Word by Word: Yesterday am not-worked.

    In the past tense, ne- attaches to the main verb (nepracoval), not the auxiliary (jsem).

  5. Nikdo nic neví.

    Nobody knows anything.

    Word by Word: Nobody nothing not-knows.

    An example of Czech double negation. The verb must be negative because of the negative pronouns.

Common Mistakes

  • Forgetting double negation (Negative Concord) when using words like nobody or nothing.

    Nikdo ví.
    Nikdo neví.

    In Czech, if you use a negative pronoun like nikdo (nobody) or nic (nothing), the verb must also have the ne- prefix. Multiple negatives do not cancel each other out.

  • Putting the negative prefix on the wrong word in the past tense.

    Nejsem dělal.
    Nedělal jsem.

    In the past tense, the ne- prefix attaches to the main verb (the one ending in -l), not to the auxiliary verb (jsem, jsi, etc.).

To understand verb negation, learners first need to be familiar with the basic negative particle 'ne' and the concept of verb conjugation in the present tense, as the prefix 'ne-' is attached directly to these conjugated forms.
