There are five verb classes in Czech. Each Czech verb belongs into one of
those five classes (there are few irregular verbs, however). Each class, or
conjugation, has its own specific set of endings that you should learn by heart.
To help you with deciding which class a verb belongs to, you need to know its
present tense form of the 3rd person singular and its infinitive. The following
table is simplified for the purposes of the class.
nést (carry, bear)
začít (begin, start)
jmenovat (se) (to be called/named)
mluvit (to speak)
znát (to know)
1st person sg (já)
2nd person sg (ty)
3rd person sg (on, ona, ono)
1st person pl (my)
2nd person pl (vy)
3rd person pl (oni, ony, ona)
The endings for the first and second class are identical, except the inserted
-n- in the second class.
'Markers' that will help determine the conjugation of a verb are -e-
in the 1st and 2nd classes, -je- in the 3rd class, -í- in the
4th class and -a- in the 5th class.
Another help is the infinitive. Verbs ending with -at, -át are usually
in the 5th class; -it- is usually 4th class; -ovat is always
To conjugate a verb in the present tense, take away the infinitive ending
and add the present tense endings. However, some verbs are irregular.
