Czech verbs of motion, also called determinate and indeterminate verbs, is a special grammar category which deals with verbs indicating movement. Such verbs have two different imperfective forms which work similarly like the English Present Simple and Present Continuous tenses.

běhat
regularly
determinate verb
Present Simple - Regular Activity
běžet
right now
indeterminate verb
Present Continuous - Ongoing Activity

Determinate verbs (běhat) usually behave like the Present Simple tense, expressing habitual situations or general always true facts.

Rád běhám v parku.

Každý den běhám na autobus.

Indeterminate verbs (běžet), on the other hand, work like Present Continuous tense, meaning the verb is being performed at the moment of speaking.

Je 8 ráno a běžím pozdě do práce.

Zrovna teď běžím kolem přehrady.

More verbs of motion: (determinate – indeterminate)

  • chodit – jít
  • jezdit – jet
  • létat – letět
  • nosit – nést
  • vodit – vést
  • vozit – vézt
  • tahat – táhnout

The future tense is formed by adding po- prefix to the indeterminate form.
The past tense is also typically formed from the indeterminate verb, however, no prefix is used.

poběžím – běžel jsem

pojedu – jel jsem

poletím – letěl jsem

ponesu – nesl jsem
