Lesson 40 – Perfective & Imperfective

Welcome to Lesson 40! Today, we’re tackling one of the most important (and sometimes tricky) aspects of Polish grammar: perfective and imperfective verbs. Understanding these two verb forms will help you express actions more accurately, whether they’re ongoing, completed, or habitual. Let’s break it down step by step!

What Are Perfective and Imperfective Verbs?

In Polish, verbs come in two aspects:

1. Imperfective (niedokonane) – Describes actions that are ongoing, repeated, or habitual.
2. Perfective (dokonane) – Describes actions that are completed or have a clear result.

Think of it like this:

• Imperfective = in progress or no clear end.
• Perfective = finished or result achieved.

Key Differences & Examples

Here’s a quick comparison of some common verbs in both aspects:

Usage in Sentences

Let’s see how these verbs work in real-life sentences:

Imperfective Examples:

1. Czytałem książkę przez godzinę.
   (I was reading a book for an hour.)
   • The action is ongoing, with no clear completion.
2. Ona robi obiad.
   (She is making dinner.)
   • The action is in progress.
3. Codziennie piszę listy.
   (Every day, I write letters.)
   • The action is habitual or repeated.

Perfective Examples:

1. Przeczytałem książkę.
   (I finished reading the book.)
   • The action is completed.
2. Ona zrobiła obiad.
   (She has made dinner.)
   • The action is finished, with a clear result.
3. Napisałem list wczoraj.
   (I wrote a letter yesterday.)
   • The action is a one-time completed event.

Key Tip: When to Use Which Aspect

• Use imperfective verbs for:
  • Actions in progress (e.g., „Czytam książkę.” – I am reading a book.)
  • Repeated or habitual actions (e.g., „Codziennie jem śniadanie.” – I eat breakfast every day.)
  • Actions with no clear end (e.g., „Uczę się polskiego.” – I am learning Polish.)
• Use perfective verbs for:
  • Completed actions (e.g., „Przeczytałem książkę.” – I finished reading the book.)
  • One-time actions with a clear result (e.g., „Zrobiłem zadanie.” – I did the homework.)

Practice Tasks

Let’s reinforce what you’ve learned with some exercises!

Task 1: Match the Verbs
Match the imperfective verbs to their perfective counterparts:

1. pisać
2. jeść
3. mówić
4. czytać
5. robić

a. powiedzieć
b. zjeść
c. przeczytać
d. napisać
e. zrobić

Task 2: Choose the Correct Aspect
Fill in the blanks with the correct form of the verb (imperfective or perfective):

1. „Ona __________ (czytać/przeczytać) książkę wczoraj.”
2. „Codziennie __________ (jeść/zjeść) śniadanie o 8 rano.”
3. „On __________ (robić/zrobić) zadanie w godzinę.”

Task 3: Create Your Own Sentences
Write 3-5 sentences in Polish using both imperfective and perfective verbs. For example:

• „Wczoraj napisałem email.” (Yesterday, I wrote an email.)
• „Codziennie czytam gazetę.” (Every day, I read the newspaper.)

Grammar Tip: Prefixes and Suffixes

Perfective verbs are often formed by adding a prefix or changing the suffix of the imperfective verb. For example:

• czytać (to read) → przeczytać (to finish reading)
• pisać (to write) → napisać (to finish writing)

While there are patterns, some verbs are irregular, so it’s best to learn them in pairs.

Cultural Insight: Polish Precision

Polish speakers pay close attention to verb aspects because they convey important details about the action. Using the correct aspect shows that you understand the nuances of the language, which will impress native speakers!

• You now know when to use each aspect in sentences.
• You’ve practiced identifying and using both forms.
