Apart from the subject, many verbs have other complements. Some need these complements in order to form sentences that make sense. These complements are called objects. They can be people or things.
In German, many verbs require an object in the accusative. If the accusative object has an article, this is formed as follows:
The accusative object answers the question "Wen?" or "Was?" (wen for people and was for things).
Some verbs that require an accusative object are: essen, trinken, nehmen, suchen, kennen, machen, lieben, anrufen, besuchen, besichtigen, …
Grammatical terms in German:
das Objekt: The object refers to a person or thing that is the aim of an action or event. The object is also known as the complement. It is usually a noun or pronoun.
A noun can have different functions in a sentence. For example, it can be subject or object. Depending on what function the noun has, its form can change. However, this change can best be seen in the form of the article. In German, there are four different distinguishing forms or categories (cases) of noun, known as Fälle or Kasus .
One of these cases is the accusative.der Akkusativ: Most objects are in the accusative . The articles are then: den/einen, die/eine, das/ein, die/-.
