Aspect in the Past

Level 3

Every past-tense verb shows aspect: Celý večer som písal (I was writing all evening) describes the activity, while Napísal som list (I wrote the letter) reports the finished result.

How It Works

The past tense works the same way for both aspects, but the choice of verb changes the meaning. See imperfective and perfective aspect.

Imperfective past (písal, čítal, varil):

  • an activity that lasted: Celý večer som písal. (I was writing all evening.)
  • a habit: Keď som bol malý, často som čítal komiksy. (When I was little, I often read comics.)
  • a background action: Varila som, keď zazvonil telefón. (I was cooking when the phone rang.)
  • whether something ever happened: Čítal si tú knihu? (Have you read that book?)

Perfective past (napísal, prečítal, uvaril):

  • a finished result: Napísal som list. (I wrote the letter.)
  • events in a row: Vstal som, obliekol som sa a odišiel som. (I got up, got dressed and left.)
  • a single event that interrupts a background: … keď zazvonil telefón.

Quick test. Phrases of duration such as celý deň or dve hodiny go with the imperfective. A result you can count, such as celú knihu or tri listy, usually goes with the perfective. See how long and how often.

Examples (6)

  1. Celý večer som písal.

    I was writing all evening.

    Word by Word: Whole evening (I-am) wrote(impf).

    The activity lasted, so the imperfective písal.

  2. Napísal som list.

    I wrote the letter.

    Word by Word: I-wrote(pf) (I-am) letter.

    The letter is finished, so the perfective napísal.

  3. Keď som bol malý, často som čítal komiksy.

    When I was little, I often read comics.

    Word by Word: When I-was little, often I-read(impf) comics.

    A habit in the past takes the imperfective.

  4. Varila som, keď zazvonil telefón.

    I was cooking when the phone rang.

    Word by Word: I-cooked(impf) when rang(pf) phone.

    Varila is the background; zazvonil is the event that happened.

  5. Včera som prečítal celú knihu.

    Yesterday I read the whole book.

    Word by Word: Yesterday I-read-through(pf) whole book.

  6. Čítal si už tú knihu?

    Have you read that book?

    Word by Word: Read(impf) you already that book?

    The imperfective asks whether it ever happened, not about a result.

Common Mistakes

  • Using a perfective verb with a phrase of duration.

    Celý deň som napísal list.
    Celý deň som písal list.

    Celý deň describes how long the activity lasted, so use the imperfective písal. Napísal would report only the finished result.

  • Using a perfective verb for a past habit.

    Keď som bol malý, často som prečítal komiksy.
    Keď som bol malý, často som čítal komiksy.

    Často describes a repeated habit, which needs the imperfective.

  • Using a perfective verb for a background action (intended meaning: I was in the middle of cooking).

    Uvaril som, keď zazvonil telefón.
    Varil som, keď zazvonil telefón.

    The cooking was in progress when the phone rang, so it needs the imperfective varil. Uvaril som would say the cooking was already finished.
