You already know how to identify the subject of a sentence using the nominative case. The subject is the star of the show, the one performing the action. But who or what is on the receiving end of that action? That’s where the accusative case comes in.

The accusative case marks the direct object. Think of it this way: the nominative subject does something, and the accusative direct object has something done to it. It directly receives the action of the verb.

The good news is that articles and pronouns only change in the masculine form when switching from nominative to accusative. Feminine, neuter, and plural forms stay exactly the same. This makes things much easier to remember.

Notice how only the masculine articles der and ein change to den and einen. Let's see this in action.

• Ich kaufe einen Tisch. (I am buying a table.)
• Sie liest das Buch. (She is reading the book.)
• Er hat eine Katze. (He has a cat.)

In the first sentence, Tisch is masculine, so the indefinite article ein becomes einen. In the others, Buch (neuter) and Katze (feminine) don't require any changes to their articles.

Just like articles, personal pronouns also have a special form for the accusative case. When 'I' becomes the object 'me', or 'he' becomes 'him', you're essentially using the accusative case in English. German does the same thing, but with its own set of pronouns.

Look at these examples:

• Er fragt mich. (He asks me.)
• Ich sehe dich. (I see you.)
• Wir besuchen ihn. (We visit him.)

Certain verbs, called transitive verbs, almost always need a direct object to make sense. Verbs like haben (to have), sehen (to see), kaufen (to buy), lesen (to read), essen (to eat), and lieben (to love) all take the accusative.

Finally, some prepositions will always force the noun that follows them into the accusative case, no matter what. There’s no need to wonder about subjects or objects; if you see one of these prepositions, the noun that follows is accusative. A common acronym to remember them is DOGWUF.

• Ich gehe durch den Park. (I walk through the park.)
• Sie kauft ein Geschenk für ihn. (She buys a gift for him.)
• Wir fahren um die Stadt. (We drive around the city.)

In each case, the preposition determines the case of the noun that follows it.

Let's check your understanding.

Mastering the accusative case is a huge step. It allows you to build more complex and interesting sentences by clearly defining who is doing what to whom.
