Questions & Answers about Zimne napoje są w kuchni.
Why is the adjective zimne instead of zimni?
In the plural, Polish separates nouns into two groups: "men" (masculine personal) and "everything else" (non-masculine). Because napoje (drinks) are inanimate objects, they belong to the "everything else" group. Therefore, the adjective takes the -e ending (zimne).
What is the singular form of napoje and why does the vowel change?
The singular form is napój. When adding the plural -e ending, the ó changes back to an o to make napoje. This ó to o vowel shift is very common in Polish when adding endings to make a short word longer.
Why is the word for kitchen spelled kuchni here instead of kuchnia?
Because it describes a location ("in the kitchen"), the preposition w requires the Locative case. For feminine nouns that end in -nia like kuchnia, the Locative case ending is -ni, which gives us w kuchni.
