Review Summary

  • Prefix + Imperfective Verb = Perfective Verb

Errores comunes

Using the imperfective 'psal' implies you were writing it, but doesn't confirm you finished. Use 'napsal' for the completed result.

Wrong: Včera jsem psal ten dopis. (When meaning the letter is finished)
Correcto: Včera jsem napsal ten dopis.

Perfective verbs cannot express the present moment. 'Udělám' actually means 'I will make'. Use the imperfective 'dělám' for current actions.

Wrong: Teď udělám kávu. (Thinking it means 'I am making coffee now')
Correcto: Teď dělám kávu.

Choosing the wrong prefix changes the meaning. 'Zapít' means to wash something down with a drink, while 'vypít' means to finish the drink.

Wrong: Zapil jsem kávu. (When meaning 'I finished my coffee')
Correcto: Vypil jsem kávu.
