Starting And Stopping Actions

Level 3

Phase verbs like zacząć (to start) or przestać (to stop) describe the timing of an action. In Polish, the verb that follows them must be in the imperfective aspect.

How It Works

Phase verbs (czasowniki fazowe) are used to indicate the beginning, continuation, or end of an activity.

1. The Imperfective Rule
The most important rule is that the infinitive following a phase verb must be imperfective. Even if the phase verb itself is perfective (e.g., zacząłem - I started), the action being started is viewed as a process (e.g., pisać - writing).

2. Common Phase Verbs

  • Zacząć / zaczynać (to start)
  • Skończyć / kończyć (to finish/complete): Used when a task is brought to its conclusion.
  • Przestać / przestawać (to stop/cease): Used when an activity or state ends, such as a habit or a natural phenomenon (e.g., Przestało padać - It stopped raining).

3. Expressing Continuation
While English uses "continue to do," the Polish verb kontynuować usually takes a noun (e.g., kontynuować pracę). To express continuing an action with a verb, it is much more natural to use the adverb dalej (further/still) followed by a conjugated verb: On dalej czyta (He continues reading/He is still reading).

4. Aspect of the Phase Verb
While the second verb is locked in the imperfective, the phase verb itself changes based on aspect rules:

  • Zacząłem czytać (I started reading - a specific past event).
  • Zawsze zaczynam czytać wieczorem (I always start reading in the evening - a habit).

5. Noun vs. Infinitive
Note that verbs like zacząć and skończyć can also take a noun in the Accusative case (e.g., Skończyłem zupę - I finished the soup). However, przestać cannot take a noun in the Accusative; it must be used with an infinitive or a prepositional phrase. Use the infinitive when you want to specify the action (e.g., Skończyłem jeść zupę - I finished eating the soup).

  1. Zacząłem uczyć się polskiego w zeszłym roku.

    I started learning Polish last year.

    Word by Word: I-started to-learn self Polish in last year.

    Even though 'zacząłem' is perfective, the following verb 'uczyć się' must be imperfective.

  2. Przestań wreszcie narzekać!

    Stop complaining finally!

    Word by Word: Stop finally to-complain!

    The imperative 'przestań' is followed by the imperfective infinitive 'narzekać'.

  3. Skończyliśmy sprzątać mieszkanie o północy.

    We finished cleaning the apartment at midnight.

    Word by Word: We-finished to-clean apartment at midnight.

    The action of cleaning is viewed as a process that reached its end.

  4. Oni dalej pracują nad projektem.

    They continue to work on the project.

    Word by Word: They further work over project.

    Instead of using 'kontynuować' with an infinitive, Polish speakers naturally use 'dalej' (further) with a conjugated verb.

  5. Kiedy zaczniesz pisać ten list?

    When will you start writing this letter?

    Word by Word: When you-will-start to-write this letter?

    Even in the future, the phase verb governs an imperfective infinitive.

Common Mistakes

  • Using a perfective infinitive after a phase verb.

    Skończyłem napisać list.
    Skończyłem pisać list.

    Learners often use 'napisać' (perfective) to show the letter was finished, but the verb 'skończyć' already conveys completion. The following verb must be the imperfective 'pisać'.

  • Adding 'do' or 'żeby' before the infinitive.

    Zacząłem do czytać.
    Zacząłem czytać.

    Unlike English ('start to read'), Polish does not use a particle between the phase verb and the infinitive.
