Questions & Answers about Der Mantel hängt am Haken im Flur.
Why is Der Mantel capitalized and preceded by Der?
In German, all nouns are capitalized. Mantel is a masculine noun and, in this sentence, functions as the subject. A masculine noun in the nominative case takes the definite article der, hence Der Mantel.
Why is the verb written as hängt with an umlaut and ending in -t?
The base form is hängen (“to hang”). In the present tense third-person singular, German weak (regular) verbs normally add -t (er macht, er spielt). However, hängen also undergoes a stem-vowel change a → ä in the du/er-sie-es forms. So hängen becomes er hängt.
What’s the difference between hängen and aufhängen?
hängen (intransitive) describes something that is already hanging: Der Mantel hängt (“The coat is hanging”).
aufhängen (transitive) means “to hang something up”: Ich hänge den Mantel auf (“I hang the coat up”).
Why is it am Haken instead of an den Haken?
The preposition an can take either accusative or dative. With a static location (“on the hook”), you use the dative case: dem Haken. An + dem contracts to am. If you express motion toward the hook (“onto the hook”), you would use the accusative: an den Haken.
