Questions & Answers about Ten robotnik codziennie nosi ciężki materiał na budowę.
Why use nosi here instead of niesie?
nosi is the multidirectional or habitual form of the verb to carry. Because the sentence includes codziennie (every day), it describes a repeated, habitual action. If the worker were carrying the material just one time right now, we would use the unidirectional form niesie.
I thought the object of a verb takes the accusative case. Why doesn't ciężki materiał change its ending?
It actually is in the accusative case! Materiał is a masculine inanimate noun. For masculine inanimate nouns (and their adjectives, like ciężki), the accusative form is identical to the nominative (dictionary) form. The ending would only change if it were a masculine animate noun, like an animal or a person.
Why is it na budowę instead of na budowie?
The preposition na takes the accusative case (budowę) when it shows motion or direction toward a destination, like carrying something to the site. If the sentence was about an action happening at or inside the site without moving there from the outside, it would use the locative case (na budowie).
I learned before that nosić means to wear. Is it the exact same verb?
Yes, it is the exact same verb! In Polish, nosić means both to carry and to wear (you can think of wearing clothes as carrying them on your body). The context of a worker and heavy material makes it obvious that it means carries in this specific sentence.
