Learn Hardcore German: Willkommen in der Stadt.

The preposition in is one of German’s two-way prepositions. It takes the accusative when the sentence indicates movement toward a destination, but it uses the dative when describing a location. In Willkommen in der Stadt, the phrase shows where someone is (a static location) rather than where they’re going, so the dative case is used.

What is the grammatical function of Willkommen in this sentence?

Willkommen functions as an interjection or an adjectival greeting. It essentially acts like a standalone welcome, similar to English where you might simply say Welcome! Even though it is originally an adjective, here it’s used without a linking verb to greet someone directly.

Why is Willkommen capitalized, even though adjectives are not normally capitalized in German?

In German, the first word of any sentence is capitalized. Additionally, in fixed expressions or greetings like this one, Willkommen can sometimes be seen as having a nominal function. However, the primary reason for the capitalization is that it begins the sentence.

Why does the article for Stadt appear as der instead of die?
