“How do German cases work?”
German has four grammatical cases: nominative (subject), accusative (direct object), dative (indirect object), and genitive (possession). The case determines the form of articles and adjectives. For example, "the dog" is "der Hund" as a subject but "den Hund" as a direct object.

Questions & Answers about Ich gehe in den Park.
Why is it in den Park instead of in der Park?
In German, the article der changes to den in the accusative case. When indicating movement toward someplace (here, going into the park), you use the accusative case. Hence, der Park becomes den Park after the preposition in when there is a sense of direction.
Why do we say ich gehe rather than ich gehe zu or ich fahre?
Ich gehe means I go on foot or I walk. You could use other verbs like ich fahre if you’re driving or riding a bike, or ich gehe zu if you’re going to a person or vague location. But here, we specifically say ich gehe in den Park to emphasize walking into the park as a destination.
How do I know when to use the preposition in versus something like zu or nach?
Use in when you are entering an enclosed space or a defined area, like a building (in das Haus) or a park (in den Park). Zu is often used for movement toward people or specific places like stores (zu dem Bäcker, commonly contracted to zum Bäcker). Nach is typically for proper geographical names (nach Berlin, nach Europa).
Why is Park capitalized?
All nouns in German are capitalized. Park is a noun, so it follows the rule and must be written with a capital P.
Are there other ways to say I go to the park?
Yes. For instance, you could say Ich laufe in den Park (I walk to the park) or more casually Ich gehe zum Park, though zum Park slightly shifts the meaning to toward the park rather than into the park itself. The choice depends on the nuance you want to convey.
