Questions & Answers about Inne klucze są na biurku.
How did klucz (key) become klucze in the plural?
Klucz is a masculine noun for an inanimate object. For non-virile nouns that end in a "soft" consonant sound like -cz, -sz, or -rz, the plural ending is usually -e. Therefore, klucz becomes klucze.
I learned that klucz is a masculine noun. Why is it using a "non-virile" plural form?
In the plural, Polish simplifies its genders into just two main categories: "virile" (groups that include at least one male human) and "non-virile" (literally everything else: women, animals, objects, concepts). Since a key is an object, it falls into the non-virile category in the plural, even though it is masculine in the singular!
Why is the word for "other" written as inne here?
Because it is describing klucze, which is a non-virile plural noun. In Polish, adjectives describing plural non-virile nouns end in -e. The basic dictionary form of the word is inny, and its non-virile plural form is inne.
Why does the sentence say na biurku instead of na biurko?
The preposition na (on) is followed by the Locative case when you are talking about a static location (where something currently is). Biurko is a neuter noun, and in the Locative case, it takes the ending -u, becoming biurku.
