Slovesa dokonavá a nedokonavá (completed and
incompleted verbs)
In the Czech language, verbs are divided into two basic categories based
on aspect: dokonavý (perfective) and nedokonavý (imperfective). This
distinction helps express whether an action is completed or ongoing. Here’s
an easy way to understand it:
1. Nedokonavý (Imperfective): Ongoing, habitual, or
repeated actions
These verbs describe actions without focusing on whether they are
completed. They can express:
Ongoing actions: Something happening right now.
o Dělám domácí úkol. = I am doing homework.
Habitual actions: Something you do regularly.
o Každý den chodím do školy. = I go to school every day.
Unfinished actions: When the focus is not on finishing.
o Četl jsem knihu. = I was reading a book (but we don’t know if I
finished).
Nedokonavý verbs can also be used in all tenses (past, present,
future).
2. Dokonavý (Perfective): Completed or one-time
actions
These verbs focus on actions that have been (or will be) completed.
They often answer the question "What happened?"and are used for:
One-time, finished actions: Something that has a clear endpoint.
o Udělám domácí úkol. = I will do (complete) my homework.
Results: When the action is finished, and the result matters.
o Přečetl jsem knihu. = I read (and finished) the book.
Dokonavý verbs do not have a present tense. If you try to express
the present with a perfective verb, it will imply the future:
Půjdu do školy. = I will go to school.
How to Recognize Them
Often, the same verb root has two forms: one imperfective and one
perfective. The perfective form is usually created by adding prefixes or
slightly modifying the root.
o psát (to write, imperfective) → napsat (to write, perfective)
o číst (to read, imperfective) → přečíst (to read, perfective)
If you're not sure which to use:
Use nedokonavý for everyday or ongoing activities.
o Učím se češtinu. = I am learning Czech.
Use dokonavý for specific goals or completed actions.
o Naučil jsem se češtinu. = I have learned Czech (I’m done).
How to Distinguish Dokonavý vs. Nedokonavý
Prefixes: Many perfective verbs are formed by adding
prefixes to an imperfective root. Common prefixes include:
1. na-, po-, z(e)-, vy-, do-, pře-, od-, etc.
1. psát (to write, imperfective) → napsat (to write, perfective)
2. jíst (to eat, imperfective) → sníst (to eat up, perfective)
Suffixes: Sometimes, a suffix can indicate imperfective verbs
derived from a perfective verb.
1. napsat (perfective) → napisovat (imperfective)
2. přečíst (perfective) → přečítat (imperfective)
Present Tense Test:
1. If a verb can be used in the present tense, it is imperfective
(nedokonavý).
1. Čtu knihu. (I am reading a book) → Imperfective.
2. If a verb in the “present tense” expresses the future, it is
perfective (dokonavý).
1. Přečtu knihu. (I will read the book) → Perfective.
Focus of the Sentence:
1. If the focus is on the process or duration, it’s imperfective.
1. Maloval obraz celý den. = He was painting the picture all
day.
2. If the focus is on the result or completion, it’s perfective.
1. Namaloval obraz během jednoho dne. = He painted
(finished) the picture in one day.
