This is the 2941st most frequent Polish word.
nazwę
"Name" (accusative form).
The word 'nazwę' here is the accusative singular form of 'nazwa', which means 'name', used as the object of the verb.
Myślę o nazwę dla mojego nowego projektu.
I am thinking about a name for my new project.
In this sentence, 'nazwę' is in the accusative case and is the direct object of the action described by the verb 'nadałem' (I gave).
Nadałem nazwę mojej firmie.
I gave a name to my company.
Here, 'nazwę' is used within a question to denote the object being inquired about, again as an accusative form of the noun.
