Learn Hardcore Polish: Oni będą oglądać film jutro wieczorem. - They will watch a movie tomorrow evening.

The sentence uses a compound future tense. The auxiliary verb będą (the third person plural future of być, “to be”) is paired with the infinitive oglądać (“to watch”). This structure is typical when forming the future with imperfective verbs in Polish.

Why is the main verb oglądać in its infinitive form rather than conjugated?

In the compound future construction for imperfective verbs, the main verb remains in the infinitive. This is because the future is expressed by the auxiliary będą while the action itself is indicated by the infinitive oglądać.

What does the subject Oni represent, and could it be omitted?

Oni means “they” (referring to a group of males or a mixed-gender group). Although Polish often allows for the omission of subject pronouns due to verb conjugations implying the subject, it is included here to provide clarity, especially for learners.

How do jutro and wieczorem function in this sentence?

Jutro translates as “tomorrow” and wieczorem means “in the evening.” Together, they form a time expression that specifies when the action will take place. The order—day followed by part of the day—is standard in Polish time expressions.

Why does the noun film not change form in this sentence?

In Polish, many masculine inanimate nouns have the same form in both the nominative and accusative cases. Since film is a masculine inanimate noun (and a loanword similar to the English “film”), its form remains unchanged when it functions as the object of the verb.
