Questions & Answers about Der Film ist ernst.
In German, every noun has a grammatical gender: masculine, feminine, or neuter.
- Film is grammatically masculine, so it takes the article der in the nominative singular.
- You just have to learn the gender with the word: der Film (the film/movie), die Stadt (the city), das Buch (the book).
In the plural, the article would change: die Filme (the films/movies).
All nouns in German are capitalized, regardless of their position in the sentence.
- Der Film ist ernst. – Film is a noun → capitalized.
- Der alte Film ist ernst. – Film is still a noun → capitalized.
Adjectives and verbs are not capitalized (unless they start the sentence or are turned into nouns), so ernst stays lowercase here.
