Questions & Answers about Die Straße hat eine Kurve.
Because Straße is a feminine noun in German. German nouns have grammatical gender, so:
- der = masculine
- die = feminine
- das = neuter
Since Straße is feminine, its dictionary form is die Straße.
In this sentence, die Straße is also the subject, so it stays in the nominative case:
- Die Straße hat eine Kurve.
In German, all nouns are capitalized, not just proper names.
So in this sentence:
- Straße = noun
- Kurve = noun
That is why both are written with capital letters:
- Die Straße hat eine Kurve.
This is a basic spelling rule in German.
