Questions & Answers about Der Mann besitzt ein altes Buch.
What does besitzt mean, and why is it used instead of hat?
besitzen means “to own” in the sense of formal or legal possession. While haben simply means “to have,” besitzen emphasizes ownership. Both are correct (you could say Der Mann hat ein Buch), but besitzen is more precise.
Why is Der Mann in the nominative case?
Because Der Mann is the subject of the sentence—the one performing the action. In German, subjects are marked by the nominative case.
What case is ein altes Buch, and how can I tell?
It’s in the accusative case because it’s the direct object—the thing being owned. You can tell by the noun’s role (direct object) and by the article ein, which stays ein in neuter accusative singular. The adjective ending -es also signals neuter accusative.
Why does altes end with -es, not -e or -er?
Adjective endings depend on gender, number, case, and the type of article. Here, Buch is neuter singular in the accusative, and the article is indefinite (ein). In that situation, adjectives take -es, giving altes Buch.
How do adjective declensions work in general?
German adjectives change their endings to reflect:
• Gender (masculine/feminine/neuter)
• Number (singular/plural)
• Case (nominative/accusative/dative/genitive)
• Article type (definite, indefinite, or no article)
There are three declension patterns—strong, weak, and mixed—depending on whether the article already shows the case/gender ending.
Why is Buch treated as neuter?
In German every noun has a fixed grammatical gender. Buch (book) is simply one of the neuter nouns. You must learn each noun together with its article—das Buch.
Why is the verb besitzt in the second position?
German main clauses follow the V2 rule: the finite verb must appear in the second position, regardless of what comes first. Here, the subject Der Mann is first, so besitzt comes second.
Can I change the word order to emphasize something? For example, Ein altes Buch besitzt der Mann?
Yes. You can front the object (Ein altes Buch) for emphasis or stylistic reasons. The verb still stays in second position, and the subject follows the verb. The nuance shifts to highlight the book.
Are there other verbs or expressions to talk about owning something?
Yes. Aside from besitzen and haben, you might see erwerben (“to acquire”) in a more formal context, or colloquially jemandem gehört etwas (“something belongs to someone”). For example: Dem Mann gehört ein altes Buch.
