The Accusative Case in German

The Accusative case (Akkusativ) is the direct object case in German grammar. It is used to mark the person or thing that is directly affected by the action of the verb, answering the questions Wen? (Whom?) for animate objects and Was? (What?) for inanimate ones. It is also governed by specific prepositions and verbs of movement.

Morphologically, the Accusative case is notable because only masculine singular nouns, articles, and adjectives change their endings: der becomes den, ein becomes einen, and adjectives take the ending -en (e.g., den netten Mann). Feminine (die/eine), neuter (das/ein), and plural (die) forms remain identical to their Nominative counterparts, which simplifies declination significantly.

The Accusative is also used after verbs showing transition or action (like haben, brauchen, es gibt), after strictly accusative prepositions (durch, für, gegen, ohne, um), and with two-way prepositions (Wechselpräpositionen) when expressing movement toward a destination. A common mistake is forgetting to decline masculine adjectives in the Accusative, writing ich suche ein neuer Freund instead of ich suche einen neuen Freund.
