Questions & Answers about On pracuje długo w biurze i wraca wieczorem.

What does On mean in this sentence?

On is the third-person singular masculine pronoun meaning "he." Polish distinguishes between masculine, feminine, and neuter, so using on clearly indicates that the subject is a male.

How is the verb pracuje formed, and what is its infinitive?

Pracuje is the third-person singular present tense form of the verb pracować (to work). It shows that the action is currently happening and agrees with the subject on.

What role does długo play in the sentence?

Długo is an adverb that modifies the verb pracuje. It indicates the duration of the work, meaning "for a long time" or "long."

Why is the noun biurze used instead of biuro after the preposition w?

When indicating location with the preposition w (meaning "in"), the noun must be in the locative case. Biuro changes to biurze in the locative, which is why this form is used.

What does wraca wieczorem mean, and why is the subject not repeated in the second clause?

Wraca is the third-person singular present tense form of wracać (to return), and wieczorem is an adverbial phrase meaning "in the evening." In Polish, once a subject like on is established in a compound sentence, it does not need to be repeated in subsequent clauses.

What function does the conjunction i serve in this sentence?

The conjunction i means "and" and is used to join the two independent clauses—one describing the work and the other describing the return—into a single, compound sentence.
