IV. Class

Czech verbs can be classified in several ways. Verbs that belong to the same class accept the same range of suffixes.
The most common classification has five classes - I, II, IV, V. We must memorize these.

We sort each verb into one of the five groups according to the form of the 3rd person singular of the present tense.
