Questions & Answers about Die Oberfläche ist ruhig.
Why is die used before Oberfläche?
Oberfläche is a feminine noun in German. It’s also the subject of the sentence, which means it’s in the nominative case. The definite nominative singular article for feminine nouns is die.
Which grammatical case is die Oberfläche in?
It’s in the nominative case, because die Oberfläche functions as the subject of the verb ist.
Why is Oberfläche capitalized?
In German, every noun is capitalized, no matter where it appears in a sentence. That’s why Oberfläche always starts with a capital O.
Why doesn’t ruhig take an ending (like ruhige)?
When an adjective follows a linking verb such as sein (to be), it’s called a predicative adjective and stays in its base form. You only add endings when the adjective directly modifies a noun (attributive position).
Why does ist come right after Die Oberfläche rather than at the end?
German main clauses follow the “verb-second” (V2) rule: the finite verb must occupy the second position. Here the subject (Die Oberfläche) is first, the verb (ist) second.
Can ruhig mean “quiet” as well as “calm”?
Yes, but German typically distinguishes the concepts. ruhig means “calm,” “peaceful,” or “undisturbed,” often about weather or moods. still means “silent” or “without noise.”
How do you pronounce Oberfläche?
It’s pronounced [ˈoːbɐˌflɛçə]:
- Ober = [ˈoːbɐ] (“Oh‑ber,” with a short “o” and schwa [ɐ])
- fläche = [ˈflɛçə] (the ä like the “e” in “bed,” sch = [ʃ], final e = schwa [ə])
What is the plural of Oberfläche?
The plural is Oberflächen. You say die Oberflächen for “the surfaces.”
How would you say “A surface is calm” using an indefinite article?
Since Oberfläche is feminine, the indefinite nominative article is eine, so you say: Eine Oberfläche ist ruhig.

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.
