Questions & Answers about Bez podręcznika będziesz powtarzać ten materiał cały dzień.
Why is cały dzień used without any prepositions here?
This is the bare Accusative of continuous extent. When you want to express that an action lasts for an entire uninterrupted period (like 'all day', 'all night', or 'the whole year'), Polish uses the Accusative case with no preposition. It acts as an adverbial phrase of time.
Both ten materiał and cały dzień are in the Accusative case here. Why do they look exactly like their dictionary forms?
Both materiał and dzień are masculine inanimate nouns. For masculine inanimate nouns, as well as their modifying adjectives or pronouns like ten and cały, the Accusative case is always identical to the Nominative form. Even though they look unchanged, their grammatical role in the sentence makes them Accusative.
Could I use the perfective verb powtórzyć in this sentence instead?
No, because the phrase cały dzień (all day) heavily emphasizes the ongoing, continuous duration of the activity. Uninterrupted, prolonged actions require an imperfective verb. Therefore, you must use the imperfective future form będziesz powtarzać (you will be reviewing) rather than the perfective powtórzysz (you will finish reviewing).
Why is podręcznik in the Genitive case (podręcznika) at the beginning of the sentence?
