Questions & Answers about Zatwierdziliśmy projekt, chociaż infrastruktura nad rzeką Wisłą jest stara.
Why are both rzeką and Wisłą in the Instrumental case here?
The preposition nad (on/by the water) takes the Instrumental case to show a static location. Because rzeka (river) is a generic geographic noun, the specific name Wisła must agree with it and take the exact same case. This is why both change, becoming nad rzeką Wisłą.
If the rule says the proper name matches the generic noun's case, why is the country rule different, like w państwie Polska?
That is the main exception you are learning in this lesson! Generic nouns for cities, rivers, and mountains (like miasto or rzeka) force the proper name to match their case. However, generic words for countries (like państwo or kraj) leave the country name in its default Nominative form.
Why do we use nad for 'on the Vistula river' instead of na?
In Polish, to say something is located 'on' or 'by' the shore of a body of water (like a river, lake, or sea), you must use nad. Using na rzece would imply the infrastructure is physically floating directly on top of the water's surface.
Why does projekt look like it is in the Nominative case when it is the direct object being approved?
It is actually in the Accusative case, which is required for a direct object. However, projekt is a masculine inanimate noun, and for these specific nouns, the Accusative form is identical to the Nominative form.
