Question 1

What is the function of on in this sentence and do I always need to include it?

Accepted Answer

on is the 3rd person masculine singular pronoun in the nominative case, serving as the subject (“he”). Because Polish verbs are conjugated, you can drop on and still say Pracuje dobrze (“He works well”). Including on adds clarity or emphasis, especially in contrastive contexts.

Question 2

Why do we use dobrze instead of dobry?

Accepted Answer

dobrze is an adverb meaning “well,” and adverbs modify verbs. dobry is an adjective meaning “good” and would modify a noun. Since we’re describing how he works, we need the adverb dobrze.

Question 3

How do I know that pracuje is the present tense, 3rd person singular form of pracować?

Accepted Answer

Polish verbs change their endings for person and number. For pracować (“to work”) the present-tense paradigm is:
 • ja pracuję (I work)  
 • ty pracujesz (you work)  
 • on/ona/ono pracuje (he/she/it works)  
The ending -uje signals 3rd person singular present.

Question 4

Why is there no direct object after pracuje? Doesn’t “to work” require something to work on?

Accepted Answer

In Polish, pracować can be intransitive (just “to work”) or transitive (“to work on something”). Here it’s intransitive: On pracuje dobrze means “He works well,” with no object needed. To specify what he works on, you’d add a phrase in the appropriate case, e.g.:  
On pracuje nad projektem. (“He works on the project.”)

Question 5

Can I omit the pronoun on?

Accepted Answer

Yes. Polish verbs carry the subject information themselves.  
• On pracuje dobrze. (with pronoun, for emphasis)  
• Pracuje dobrze. (without pronoun, still “He works well”)

Question 6

How would I make this sentence negative?

Accepted Answer

Place nie immediately before the verb:  
On nie pracuje dobrze.  
This means “He does not work well.”

Question 7

How can I turn this into a question?

Accepted Answer

Two common ways:  
1. Add Czy at the beginning:  
   Czy on pracuje dobrze?  
2. Rely on rising intonation only:  
   On pracuje dobrze?  
Both mean “Does he work well?”

Question 8

Is On pracuje dobrze talking about a regular habit or about right now?

Accepted Answer

Polish present tense covers both habitual and ongoing actions. Context tells you which:  
• Habitual: On pracuje dobrze w tej firmie. (“He works well at this company.”)  
• Ongoing: Zobacz, on teraz pracuje dobrze. (“Look, he’s working well now.”)

Question 9

Why aren’t there articles like “the” or “a” in front of on or pracuje?

Accepted Answer

Polish has no definite or indefinite articles. Concepts of “a” or “the” are expressed by context, word order, or additional words, so you simply say On pracuje dobrze without any article.

Question 10

What aspect is the verb pracuje, and how would I refer to a completed action?

Accepted Answer

pracować is an imperfective verb, indicating ongoing or habitual action. To talk about a completed action, you’d switch to a perfective construction, for example:  
On dobrze wykonał pracę. (“He performed the job well.”)

On pracuje dobrze.
