Negation (Zápor)
Negation in Czech is very straightforward, but it has one feature that English speakers find strange: Double Negation.
Visual Overview​
1. Verbal Negation​
To negate a verb, simply add the prefix ne- to it. It is written as one word.
- Mám (I have) → Nemám (I don't have)
- Dělám (I do) → Nedělám (I don't do)
- SpÃm (I sleep) → NespÃm (I am not sleeping)
Exception​
The verb být (to be) in the 3rd person singular is irregular.
- Je (He is) → Nenà (He is not) - Not "neje"!
- (But: Nejsem, nejsi, nejsme... are regular).
2. Double Negation (Negative Concord)​
In Czech, if you use a negative pronoun (nobody, nothing, never), you MUST also negate the verb.
- Nikdo nic neviděl. (Nobody saw nothing. = Nobody saw anything.)
- Nikdy to neudělám. (I will never do it.)
- S nikým nemluvÃm. (I am not talking with anyone.)
Logic: "Negative subject + Negative verb".
