Questions & Answers about Dziecko biega w parku.
Why does the word park change to parku here?
To express location after the preposition w (in), we must use the Locative case. Usually, masculine nouns add -e in this case. However, because park ends in the letter k, adding an -e would change the sound awkwardly. Masculine nouns ending in -k, -g, or -ch take the ending -u instead.
Could I use na instead of w for 'in the park'?
No, you have to use w. While na is generally used for open, outdoor spaces (like na ulicy - on the street), park is an exception. In Polish, you are considered to be 'inside' a park (w parku).
The translation says 'is running'. Is there a different word for just 'runs'?
No, Polish uses the exact same present tense verb for both! The word biega translates to both 'is running' (happening right now) and 'runs' (a regular habit). You just rely on the context of the conversation to know which one is meant.
What gender is the word dziecko (child)?
It is a neuter noun, which you can usually guess by the typical -o ending. Because the child is the main subject doing the action in this sentence, the word stays in its basic dictionary form.
